03/05/12 Tried to fix endless loop caused by illegal "%(...)" script.
03/12/12 Fixed problem in @yoy() that was causing access violations.
03/20/12 Fixed problem in @Xchwt() that occured when the fdates range did not include the chain weight base year.  
03/27/12 Fixed broken menu item in editor (Insert Text From File).
03/28/12 Improved error detection in ls command.  Fixed memory leaks in chwt and chain.
04/02/12 Fixed parsing problems in "str parse".  Added "function clear [<name>]".
04/04/12 Modified @mean() and @stdev() to have the @ggr() syntax and fixed some problems in all three.  Improved error return codes in rhs.cpp.
04/04/12 Tweaked output of lis/lnc.  Fixed EOF problem with fadd.
04/12/12 Fixed problem in graph command so that 7 series may be shown.  Add counter check in chain routines to prevent overflow when reading series names.  Increased
            MAXCHAIN to 1500.
04/13/12 In %s(<string>[,<first>[,<last>]]), make <last> either the character specified or the end of the word.  Revise parsing of words within % routines so that 
            text wrapped in "" is treated as one word.  Modified treatment of unrecognized '%' in routines for which %-expansion is optional.  Increased the array size for
            chopbuf to avoid overflow.  Fixed return-code problem in %getval().  Fixed problem with setting of %xls when an empty cell is read.  Rename vector() as fvector(),
            a convention more like the existing dvector(); this avoids a conflict with STL.
04/14/12 Add wscache <on|off> or wscache <yes|no>.  When on, reading and writing to the standard workspace (ws.*) is suspended and data are held in memory.  When turned on,
            data are read from ws.*, and when turned off data are written to ws.*.  Capacity in memory is greater than on disk because of known limitations of the GBanks
            design, and so pushing data from memory to disk will fail if the ws.* bank capacity is exceeded.
04/18/12 Added wsdump <filename> [<"tdates">] to dump data to text file.  If tdates option specified, then print data within tdates.  Otherwise, strip leading and trailing
            zeros, missing values, and garbage, and just print data that appear to be valid.  Added timer <on|off> or timer <start|stop> to calculate time intervals.
            Added optional date to control extent of operations in the ls command:
             Format: ls [-<flag>] <x> <y> <date> [date2] [direction]
             <flag> may be
                a:   use 
                     x = a + b*y
                     b = x{date} / AVG(y) * sign( x{date}*AVG(y) )
                     a = x{date} - b * y{date}
                     where AVG(y) is calculated from fdate1 to <date>, if direction is 'b', or from <date> to fdate2, if direction is 'f'.  This is 
                     useful when y{date} is close to zero so that scaling parameter b is large, thus scaling x excessively.  If AVG(y) is close to 
                     zero, then b = x{date} * sign( x{date}*AVG(y) ).
                f:   force the calculation using standard algorithm without reporting problems.
                i:   if x and y are of opposite sign in the base year, use 
                     x = a + b*y
                     b = x{date} / y{date} * sign( x{date}*y{date} )
                     a = x{date} - b * y{date}
             <date2> is the last period (direction is 'f') or first period (direction is 'b') that will be modified.  If not given, then the values will be modified to the end
                     of the sereies. 
04/18/12 Added script controls for menu items added 06/09/11:  commandcache <clear>, commandcache <print>, commandcache <replay>.
04/23/12 Fixed printing problem with listnames for compressed banks.
04/30/12 Fixed divide-by-zero and other problems in chwt().
05/01/12 Make the Editor F10 (Execute) routine employ a string list rather than a temporary text file.
05/03/12 Added %if(<condition>, <if true>, <if false>) function, where specification of <condition> is identical for that of the if command.  
         <if true> and <if false> either may be named strings or text within quotes.  Added ungetword() function for internal use within utility.cpp.
         This offers unlimited capacity to store returned words and codes, though reversing course might not be possible if ungetting after a %-routine 
         has been expanded.  This is a limitation of unchop() and unfeed(), too, but there probably is no solution other than to make a copy of the original
         buffer, or perhaps to do all %-expansion separately and without inserting the expansion into the buffer.  Needs further consideration, and 
         %if() needs more testing.
05/04/12 Provide rdscale option for ctrl, with same syntax as for the scale command; must wrap group in () for rdscale option to be read.
05/08/12 Add QP extension to proportional scaling that automatically is applied when the standard algorithm fails.  Fixed problem affecting try-catch and perhaps
         other flow control routines:  unchop buffer was not getting cleared.
05/09/12 Fixed input buffer problem in vamcreate.  If the show window is closed by typing ESC, then the show exit function now will clear the ESC code to 
         prevent the script from being killed.
05/14/12 Increase limit on number of variables in matty from 30 to 100.  For now, disable 05/08/12 work on extension to proportional scaling.
05/15/12 Fix problems in syntax checking and improve messages of RAS command.
05/16/12 Added "+=" operator to str command.
05/21/12 Continued to improve messaging, error handling, and to fix bugs in RAS and related routines.  Fixed problem with alignment of data over time in 
         RAS conditions, where equations were not aligned with workspace.   
05/23/12 Rewrote much of the precon() routine.  Now allow sc(max/min) <(row group)><(column group)><value> in addition to original block specification, where
         row-column groups must have the same number of elements and must form row-column pairs that identify the desired cells.
05/24/12 Rewrote RAS routine and supporting routines to employ double-precision calculations; this fixes some convergence problems.  Need to adapt other routines
         to employ the double-precision versions of the supporting routines; meanwhile, conversion routines are in place to provide support for single-precision
         routines.
05/29/12 Make RAS routines skip conditions for which the control value is MISSING in a given period.  Added fdates command to RAS conditions command set (not 
         yet implemented for gvras routine).  
05/31/12 Fixed bug in show command.
06/12/12 Fixed some unnecessary warning messages in %if() routine.
06/15/12 Corrected and adjusted the RAS convergence check.  Improved screen output for RAS.
07/09/12 Passed a return code through the update command.  
07/24/12 Fixed problems in @min and @max, where closing ')' was not being read.  Began work to employ HTML Help files; included "htmlhelp.h".
07/25/12 Created htmlhelp.lib with "implib htmlhelp.lib hhctrl.ocx"; added to G7 directory, linked in g7.cpp.  
07/26/12 Temporarily commented line in G7.cpp; need to replace.  Got the new Help to launch, but needs more work for different menu items, command line, and
            to include methods to launch particular pages or sections.
07/26/12 Got help menu, icon, command line, and short-cut methods working and linked to appropriate locations in Help.  
08/09/12 Allow temporary series to be graphed in similar fashion to type command:  gr (<series1>) (<series2>) ...
08/10/12 Fixed up the line command to correct bugs in printing of line settings.  
08/17/12 Returned to work on xl chart routine.
08/20/12 Define 
            xl chart <col 1><row 1>...<col N><row N><direction><date 1><date 2><chart type>
08/21/12 Allow the series name to be omitted from the xl write routine; in this case the dates will be printed in Excel date format. 
08/25/12 Fixed packed matrix handling in ras command.
         Conference 2012:  7.3845

09/10/12 Began work to prevent overflow or run-on words when printing long series names with listnames commands.
09/27/12 Rewrote the listnames routine and associated routines to use STL in place of Borland containers.  Made the listnames interface dependent on a core
         routine that obtains a list of series names from the database classes.  Added -l <root> option to listnames routines to store the bank series names 
         as strings, where the string names are <root><integer> and the string definitions are the series names.  Added %nseries(<bank_letter) keyword to return 
         the number of series in the given bank.
10/02/12 Adjusted the ls routine to produce a result when the series to be moved is zero.
10/03/12 Added @sign(<expression>) that returns +-1.  
10/04/12 Fixed a problem with focus for the "file-execute" box on the main window.
10/23/12 Fixed problem in pmmuldiv() routine that caused incorrect date alignment between Vam banks and packed matrix files.  Replaced the routine that 
         expands "%{...}" with one that does proper P/E/MDAS integer arithmetic (no exponentiation, but %-routines and recursion are supported).  G7 7.3846
10/25/12 Fixed += in f and vf to handle missing values on LHS and RHS.  Added check to @chain routines to ensure that the specified base date frequecy matches
         that of the fdates.
11/08/12 Updated icon and images on splash, config, and about dialogs.  Changed Help shortcut from F2 to F1.  
11/09/12 Updated the GConfig and About windows.  Force destruction of existing Show window before a new one may be created; this finally should fix persistent 
         bugs.
11/13/12 Allow "update" as a command type for save command; previously it was the default option but could not be specified manually (except with "save off").  
11/14/12 Added Help menu links to Inforum web site.
11/15/12 Fixed crash in Editor pop-up menu Type Series when multiple lines were selected.  Added Graph Series pop-up menu item.
11/19/12 Rewrote various fill(s) routines to update pend pointer.  Reworked @-functions to update pend pointer.  This helps to fix up equation printing for r command,
         equation saving with save command, and titles for () shortcut in graph command.  Need to watch output for other routines that rely on fill(s) routines.
11/27/12 Fixed problem with expansion of %linelen.
12/05/12 Fixed problem with printing of settings with line command.
12/12/12 In Resector class, increase maximum number of sectors from 600 to 1500.
12/14/12 Tweaked gridtype.
12/17/12 In ipch command, switch from scientific notation to standard notation for printed coefficients.  Fix likely problem when printing the number of parameters 
         to be read by the model. 
01/02/13 7.3848

01/07/13 Forced writing of index file after turning off workspace cache.  In wsdump, fix problem when printing a series with only missing values, and fixed problem with
         dates that could lead to incomplete printing of data, and eliminate automatic zapping after dumping data.
04/01/13 Added %fabs(), %log(), %exp().  Allow negatives in %-function numerical arguments.
04/11/13 Attempt to fix bug in function command where an existing argument list gets lost, and thus the attempt to restore it fails.
04/12/13 In findvec, ensure that vam file is open before attempting to search it.
04/18/13 Fixed up show window save functions (still prone to failure).  Fixed f command to allow "f x{2008-%fdates2} = y".
04/24/13 In editor, LoadFromFile failed when the file was open for writing, e.g. with the save command.  Store filename in save command; check whether it is open before
         attempting to open with editor (better way to do this?).  Reworked find() to do a proper vam-file search when called by G7 routines like exists().
04/25/13 Fixed numerical problems in ls command.  
05/02/13 Redefined "xl name ws <name>" so that name is optional; if not given, then the existing worksheet name can be recovered with "%xls".  Attempted to fix
         problem with listnames command, where G bank associated with a Vam file was not searched.  Are matrix names listed?
05/16/13 Redifined BREAK and CONTINUE codes to avoid interferance with 8-bit extended ASCII representations.
05/21/13 Added "wsreset [<path>]" command to allow the workspace to be cleared and a new workspace established with new parameters and possibly in a new location.  
            If "g.cfg" is included in the path, then G7 automatically will open and read it; otherwise, the GUI will prompt the user to find and/or accept the settings
            in the optionally-specified directory.  This needs more testing.  Added sanity checks to dates in GConfig, but more is needed; sanity checking witin the GUI 
            would be nice so that the user can fix problems.  Modified feed() to check for and return characters of unchopped words; without this, unchop() followed by 
            feed() has missed the unchopped words.  G7.3849
05/23/13 Modified %xlcol(<arg>) to take either a column number and return equivalent letters or column letters and return the equivalent number.  Fixed problem in 
         %strcmp() and related functions, where the return value was not set properly.  In RunCmdFile(), add another check for error codes returned from chop().
05/28/13 Added tolerance option to ras commands (-<tolerance>), where the default value is 0.000002.
06/29/13 In ls command, now return error if series cannot be found; old practice was to add a series of missing values.
08/02/13 Added %exists(<series_name>) to return 1 (0) when a series is found (not found); the exists(<series_name>) routine provided in the if() command now is depricated.
         Added %sexists(<series_name>) to return 1 (0) when a string name is found (not found).
08/23/13 Fixed problems that prevented the opening of the InterDyme dialog.  2013 World Conference:  G7.386
09/06/13 Increased buffer size in fcmd.
10/14/13 Added frequency conversion function to GDates class.  Added frequency conversion for the printing of dates in Excel::WriteNumberArray"
12/09/13 Changed some integer variables in G7 graph routines to floats to eliminate problems when long time series caused the graph width to be compresses.  G7.3861

07/01/14 Tried to fix a bug in freq, added frequency checks to the ls command, and prevented ls from changing the frequency of a series.
08/15/14 Allow multiple series to be specified in del command.
08/16/14 Added "str store args <root>" to store function/add-file arguments to root1, root2, ....
08/20/14 Added "xl gridlines [<on|off>] [<color>]"
08/21/14 Added "xl border <fc><fr><lc><lr> <option 1> [<option2>[...]]", where options are "off", color (from list), weight (hairline, thin, medium, thick),
               position (border[default]|left|right|top|bottom|horizontal|vertical|diagonalup|diagonaldown),
               linestyle (continuous|dash|dashdot|dashdotdot|dot|double|slantdashdot).
         Added color specification "RGB(<int1>,<int2>,<int3>)" for all xl color settings (not certain that fine control is possible).
08/23/14 Added "xl printer <option 1> [<option2>[...]]", where options are <orientation> (landscape|portrait), <area> [area <fc><fr><lc><lr> | <off>], <print>
08/24/14 Added routines for managing chart sheets within a workbook.  Most routines that control worksheets (by specifying "ws" or "worksheet") now also may be used
         to control chart sheets ("ch" or "chart").  These include xl open, xl create, xl name, ....
08/26/14 Added "xl graph title ["<title>" [font <options>]"  If a title is given, then it is imposed on the active chart.  If not, the title of the active chart may
         be recovered with %xls.  The title name should be specified with surrounding quotes.  It may be followed with "font" and font options, including color,
         typeface, size, single or double underline, bold, italic.
08/27/14 Modified "xl create [before|after] <ws|ch> [<name>]" to set the postion of the new object relative to the active object; the default is "after."
         Improved the %eliteral() routine so that it can be applied more widely.
08/27/14 Added conditional formatting.
           xl cf <fc><fr><lc><lr> <number of conditions: 1-3>
               <type1> <operator> <condition1> [<operator> <condition2>]  [font <options>] [border <options>] [background <options>]
              [<type2> <operator> <condition1> [<operator> <condition2>]  [font <options>] [border <options>] [background <options>] ]
              [<type3> <operator> <condition1> [<operator> <condition2>]  [font <options>] [border <options>] [background <options>] ]
         where font options include color, bold, italic, single or double underline; border is not implemented yet; background options include color.  The number of conditions
         must match the number of rows.  Each row must begin with "value"; "formula" will be offered later.  Operators must be <=, <, ==, !=, >, >=, or !=.  If a second 
         condition is specified and the first operator is < or <=, then the second operator must be > or >= (not between), or if  the first operator is > or >=, then the second
         operator must be < or <= (between); otherwise, any second operator and condition will be ignored.  A condition may be a number, string, or cell address.
         2014 World Conference:  G7.387

09/19/14 Added setveclag <vector> [<# lags>] to get|set number of lags for a vector in the default vam file.
01/20/15 Began revisions of BankOpen GUI.  
02/03/15 Began work to allow regressions equations to be saved in G7 equation format with the "gf" option with the save command.  Change regression coefficient printing to save
         files to avoid "+ -" sequences with negative parameter values.  When addprint is off, do not print "add <filename>" statments to screen.
04/01/15 Added Close (Esc) to gridtype menu.  Fixed error message in showcmd.  Consecutive views of packed matrices in showcmd can fail to display changes
         made to the data by pmatin; force store of loaded vector at top of pmatin, as this will force all subsequent commands to reload data and thus should fix the problem.
         Added sanity checks to reading of ini file and improved default values.
04/02/15 Improved reading of g.cfg, and tried to eliminate infinite loop when valid g.cfg file was not found.
         Add check to mcopy to ensure that source bank frequency matches destination bank frequency and that both match fdates frequency or specified date range frequency.
04/10/15 Added 'c|r' option to coef to divide columns (default) | rows by the given vector.  G7.389


04/22/15 Attempt to fix memory problems related to series titles in graph routine.  
04/29/15 Attempt to fix bugs in the show and ras commands.
05/05/15 Introduce ability to read a range of dates in xl, and then recover date and components with keywords and to read a corresponding range of data with possibly 
         non-contiguous dates.
           xl read <col1> <row1> date [<col2> <row2>]          # If range is given, then either col1=col2 or row1=row2
           xl setfrequency <frequency>                         # Specify from valid G7 date frequencies: 1, 2, 4, 12 (note ambiguity with Excel dates, e.g. for quarterly frequency)
           xl read <col> <row> <direction> <series> "xldates"  # Read data, storing to given date set.
         The set of dates are stored in Excel date format, where a single date may be recovered with the %xldate keyword.  The same may be recovered in G7 date format with
         %xlgdate, or the date components may be recovered as %xlyear, %xlquarter, %xlmonth, and %xlday.
05/07/15 Fix up rs ctrlmatrows command.
05/13/15 Fixed problems in xl vecwrite.  
05/28/15 Revised coef command code to avoid numerical problems.  G7.3891
06/30/15 Attempt to fix buffer overflow problem with gtf/gti and long titles that appeared when printing data to file.
07/06/15 Attempt to fix bad printing of graph series names.
07/10/15 Fixed problems affecting xl freeze and similar commands, where changes were not made to the intended worksheet.  Make 'xl write "<>"' print floating point values or 
         integers to the spreadsheet when numbers are provided; previously, numbers were written as strings, though strings still can be forced with "'<number>".   G7.3892

08/14/15 Added keywords to read main window and editor window settings:
            %mainfontname, %mainfontsize, %mainfontcolor, %maincolor, %mainfontcharset, %mainautofontsize, %mainfontbold, %mainfontitalic, %mainfontunderline, %mainfontstrikeout, 
            %autocomplete, %edfontname, %edfontsize, %edfontcolor, %edcolor, %edfontcharset, %edfontbold, %edfontitalic, %edfontunderline, %edfontstrikeout
08/15/15 Added pause <number> to pause for a specified number of seconds, 0<=t<=1000 seconds, and then to resume.  Added run-to-cursor F11 editor shortcut.
         Added commands
            mainfontname <name>, mainfontsize <size>, mainfontcolor <color>, maincolor <color>, mainautofontsize <0|1>, mainfontbold <0|1>, mainfontitalic <0|1>, mainfontunderline <0|1>, 
            mainfontstrikeout <0|1>, autocomplete <0|1>, edfontname <name>, edfontsize <size>, edfontcolor <color>, edcolor <color>, edfontbold <0|1>, edfontitalic <0|1>, 
            edfontunderline <0|1>, edfontstrikeout <0|1>
         where font names and colors may be taken from the lists in the xl help pages and where other options may be specified as 0|1, yes|no, false|true, or off|on.
         G7.3893.


08/21/15 Make rs commands a bit more robust, and improve error messages.  Fixed bug that required number-of-sectors specifications in the rs config file
         to exceed the actual number of sectors.  
09/17/15 Initialize arrays in logit, rcmd.  In type command, correct problem with tdate_2 vs max_obs check that allowed buffer overrun.
10/08/15 Increased maximum dimensions of resector keys to 2,500 rows and 20 columns (from 1,500 rows and 10 columns).
10/09/15 Fix broken rs aggmatrix.  Change syntax to rs aggmatrix NRFrom NRowTo NColumnFrom NColumnTo FromMatrix ToMatrix to allow operations on rectangular matrices.
         In rs aggmatrix and rs aggmatrows, allow key dimensions to exceed matrix dimensions (skip excessive index values).  Try to eliminate numerical trouble in coef
         and improve checking of fdates range vs vam bank date range.
10/16/15 Fixed memory management problems in load and pmload functions.
11/04/15 Fixed a small bug in @yoy().
01/26/16 Eliminated unnecessary save prompt in G Config GUI.  Make "type (<expression>)" print the expression before printing the data.
02/11/16 Fix search for existence of series when macro bank is not linked to vam bank (affecting %exists()). 
02/12/16 Allow "%{%1}<digit> where %1 = <text><digit> (i.e. allow text within %{}; in example the %{} allows separation between the "%1" and the following integer).
03/24/16 Add Close All Banks and Assign Data Banks buttons to Currently Assigned Banks GUI.
03/28/16 Improved handling of sector titles in show (allow display of data when title files are missing).  Allow longer abreviated titles (up to 50 characters); auto-
         adjust row|column widths for longer abreviated titles.  Show full row|column title as Hint when abreviated row|column title is clicked.  Close title file
         after reading by show.  At end of show command, allow "[-rowtitle <rowtitle>] [-columntitle <columntitle>] to specify alternative title files.
04/12/16 Attempt to fix bug in vc command where (vc x = y / sum * 100) fails when size(x) > size(y).  Allow show command to substitute row|column titles from
         another file:  show <object> [<r|c|y> <row|column|year>] [[<first row>] [<year>]] [<-rt <filename>>] [<-ct <filename>>].  
04/13/16 Keep focus on Editor Find and Replace dialog boxes after execution to ease subsequent searches.  
05/03/16 In wsreset, close groups.bin file and reopen in new directory.  Fix problem with specified target directory|file in wsreset.
05/06/16 Improve function of Currently Assigned Banks GUI buttons (03/24/16).  When opening Show to a specified cell, select the cell so that pressing an arrow key
         starts navigation from the specified location.  Close Look window when associated bank is closed.  When Editor is in focus and F3 is pressed, if
         a match is found then do not shift focus to Find GUI.
05/07/16 Add "xl font <fc><fr><lc><lr> TF(<typeface>)" (TF or typeface) to allow system fonts.  Add "xl font <fr><fc><lr><lc> textwrap [off]" (textwrap or wrap) control 
         text wrapping.  Add "xl row height <row> <height>" to set row height.
05/12/16 Attempt to fix memory problems in @bmk().
06/03/16 Add "xl font <fc><fr><lc><lr> format(<format>|off)" to allow specification of general, number, currency, accounting, date, short date, 
         long date, time, percentage, fraction, scientific, text, off, or custom settings.  Complex and multiple word settings must be wrapped in "", and "off" and 
         custom settings must use the "format(<>)" syntax; other settings may be stated simply as "general" or otherwise.  Same syntax for "xl setfont".    
         Add "xl font <fc><fr><lc><lr> separator("<separator>"|off)".  The "("<separator>")" may be omitted to employ the default ",".  The setting will be stored, but it
         only will be applied to cells if a format specification has been or will be given.  Precision still is controlled by the G7 format command.
06/23/16 Modify changeDir() in attempt to fix trouble that appeared in wsb.
07/30/16 Attempt to eliminate numerical problems in @bmk(,,g) routine.
08/03/16 Added error checking in data command.
08/18/16 Improve dates check in xl routines.  In xl read, allow '"xldates"' as well as 'xldates'.  Allow empty cells within xl read dates range.  Fixed problem with xl setfrequency.
         Fixed various problems with reading an array of Excel dates.
         G7.3895.
10/06/16 Correct printing problem affecting dir command.
10/27/16 Add bank title to listbank output.  Add sanity check of precision specifications in gridtype (note:  gridtype gdp <date1><date2) sometimes caused infinite loop;
         sanity checking might help, but not clear that the problem is corrected completely).  Try again to force the graph control bar to appear in front of all other 
         windows.  Create routine to check window placement:  if the window is in a position off the visible desktop or too near the edge, reposition edge to 10 pixels
         from the edge of the desktop, and ensure that width|height is at least 10 pixels.  Check all windows created with ShowModal, as they must be closed before control
         is returned to the Main window.  Otherwise, check window placement when the Main|Windows menu item is selected.  Ensure that window size does not exceed desktop size.
11/02/16 Fixed bug in xl column addition routine that was causing xl read 1 D to read too far (so D + 230 = IZ instead of HZ).
11/11/16 Probably not used in G7, but change maximum packed matrix number from 30 to 100.
11/26/16 Modified underlying code for vc, as vc y=1/x did not work, where y and x are vectors (seemed always to calculate y=1*x).
02/14/17 7.3897
01/23/18 Fixed faulty check in show command.
05/30/18 Fix bug in %strncmpi routine.   7.3899
