Modification/New Features in  in Release 5.50E
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 1. A modification was made to ensure that .PIC files containing legend 
    information would import into major word processing programs 
    (WordPerfect, MS-Word, etc.), without problems. 

 2. The @NPV function implementation was modified so that now, if the 
    user inadvertently includes blank cells in the selected range, they 
    are ignored in the calculations of the returned value. 

 3. A correction was made to the keyboard status indicators, so that they 
    are not displayed when the {borderoff} macro is invoked.  The cell 
    reference and the flash mode indicator are not displayed, as well, 
    when the above macro is active. 

 4. The matrix inversion operation in AS-EASY-AS was amended to detect 
    singular matrices when the coefficients of one equation are simple 
    scalar offsets of the coefficients of another (by simply detecting 
    and tagging a zero determinant in the calculation). 

 5. A modification was made to re-enable the {INSON} {INSOFF} macro 
    commands. 

 6. A correction was made to the Print, preView function to treat the 
    left margin settings correctly (earlier versions used to account for 
    the left margin twice). 

 7. A modification was made to the exponential scale graphing of the 
    program.  In earlier versions, the Y-axis would revert to displaying 
    values with round-off errors (9.9E-12 instead of 1.0E-11), because 
    the value of e = 2.3025850930 was being used rather than  e = 
    2.3025850929945. 

 8. {INVALUE} and {INLABEL} macro syntax is now checked to see if matched 
    double quotes have been used, and a message is displayed if they 
    haven't. 

 9. A modification was made to the way the Range, Copy command treated 
    source "virgin" cells.  A value of zero is now assumed for all such 
    cells in the source range (target range is overwritten with zeros). 

10. The indirect cell addressing function (@@) was modified so that it 
    now may be used as an argument to the @LENGTH and the @CELL 
    functions. 

11. Two new functions were introduced in the program.  @Path returns the 
    current path and @Filename returns the name of the worksheet 
    currently loaded in AS-EASY-AS. 

12. A modification was made to the {RMDIR} macro so that it now operates 
    as expected. 

13. The Bar graph option was modified so that it now consistently 
    displays the bars, regardless of whether the upper and lower limits 
    are set automatically or manually. 

14. A correction was made so that cells formatted with the Box format 
    option are not filtered out when the /File, Option  command is used. 

15. In earlier versions of the program, trying to print combined text and 
    graphics with a "none" pitch option would produce corrupted output.  
    A warning message is now issued when the user attempts that! 

16. A correction was made to the program to now support Windows and 
    Borders, a capability that was there with Ver. 5.01 and earlier 
    versions. 

17. After a lot of thought (and user prompting), the DATE functions in 
    the program were modified to use a 200 span method (similar to some 
    other spreadsheet programs in the industry), eliminating the wrap 
    around present in earlier versions.  Here are some examples under the 
    new model: 

         @DATE(93,1,1)    =  1993
         @DATE(102,1,1)   =  2002
         @DATE(40,1,1)    =  1940
