CruX Revision Notes

 *** Version 1.52 ***  Dated 9-22-93

 1) Sort file listings in alphabetical order.

 2) Added floating point status checking to curve fitting routines.

 3) Corrected constant terms for Exponential and Logarithmic curve fits.

 4) Fixed region fill problem when printing to Postscript.


 *** Version 1.50 ***  Dated 6-15-93

 1) Added Surface plotting capability.

 2) Corrected default row displayed for X Regular Grid Row when using
    Data / Regular Grid command.

 3) Fixed problem when specifing a column width greater than 40.  Now
    allows a single column to be as wide as the spreadsheet data area.

 4) Fixed intermittant problem when exporting data to an ASCII file
    using a delimiter string with a tab (\t) as the last character.

 5) Added cell self-reference variable "@" to formula parser; Fixed
    loss of last cell in a column when a column formula re-writes to itself.

 6) Added additional control of graph border and background area.

 7) Fixed bug in Key Sort ascending sort algorithm.

 8) Added check for axis major or minor increments <= 0.0

 9) Improved missing data handling in contour plots; Cells with no data
    now produce blank area in contour, not treated as data cells with value
    of 0.

 10) Fixed bug is Data / Table that produced "Invalid Expression" error
     message when "#" was last character.

 11) Added Polar plots.

 12) Added functions to formula parser; Bessels, Error Func., Gamma, etc.

 13) Added option to force X, Y axes to be equal length for Surface plots.

 14) Fixed menu/dialog color mix-up when exiting error dialogs.

 15) Added Beta, Bessel, Chebyshev, Error, Factorial and Gamma functions to
     formula parser.


 *** Version 1.085 ***   Dated 11-29-92

1) Added Data / Statistics command.

2) For all commands that produce a summary at the bottom of a column,
	added logic to move spreadsheet view to show results upon succesful
	completion of command.

3) Added /n as a default delimiter character for command line ASCII file
   import.

4) Added Pie charts.

5) Fixed problem of lost data point when translating more than 64 values
   from Text to Number.

6) Fixed possible mis-selection of bogus data point on Graph Edit screen.

7) Added user specified execution delay when playing a macro.

8) Changed low memory warning - no longer requires a key press to continue.



 *** Version 1.084 ***   Dated 11-12-92

1) Option to return to spreadsheet upon <Ctrl><Break> from Graph View
   or Page Layout.

2) Patched GRAPHICS.LIB to fix polygon fills at resolutions above 150 DPI.

3) Allow templates originally saved with few curves to work on data
   sets with many curves.

4) Display cell reference when invalid cell found in selected range
   for Curve Fit, Sorting, etc.

5) Changed X,Y coords displayed in Graph View \ Point mode to better
	display small and large values.

6) Changed compile to produce code for 8086 family from 80286.

7) Fixed file storage of column formats which lost justification.

8) Fixed "Arithmetic Overflow" error for curve fit.

9) Changed behavior of direction/tab keys when entering data directly
   into spreadsheet to "normal"; i.e. <tab> moves right, <shift><tab> left,
   <down> moves down, etc.
