Thank you for this nice birthday present! 
Here are my first experiences (DOS and Windows interpreter).

1) Installation:
   - I installed Eu 2.4a into a directory with a long name
     ('c:\programme\euphoria'). The installation procedure then used
     long names for the PATH and EUDIR variables in 'autoexec.bat'.
     Shouldn't short names be used there?

   - I would appreciate it, if the installation procedure made a backup
     of 'autoexec.bat', before changing it. But I don't know, whether
     Inno Setup can do this.

2) dir() with wildcards and a backslash at the end of the specification:
   Thanks for fixing it. But now I detected an inconsistency.
   - Using ex.exe, 'dir("c:\\windows\\co*\\")' returned only directories
     ('COMMAND','COOKIES',...), as I expected.
   - Using exw.exe, 'dir("c:\\windows\\co*\\")' returned directories, and
     also files!

   BTW: When I run the command 'dir c:\windows\co*\' from the DOS prompt
        (DOS 7.1), an error is returned, while 'dir c:\windows\co*'
        works.

3) DOS LFN support:
   Under Windows 98/1st ed., there is less DOS LFN support with Eu 2.4a
   than with Eu 2.3:

                       +   =    LFN supported
                       -   = no LFN supported

          new file             |  -  |  -   |
   ----------------------------+-----+------+


4) I've tweaked pretty_print() a little. By just changing one line in
   rPrint(), I got the nice additional possibility 4 for the first
   option:

   ----------=----------=----------=----------=----------
   procedure rPrint(object a)
   -- recursively print a Euphoria object
       sequence sbuff
       integer multi_line, all_ascii

       if atom(a) then
           if integer(a) then
               sbuff = sprintf(pretty_int_format, a)
            -- if pretty_ascii and                            --* original
               if 0 < pretty_ascii and pretty_ascii < 4 and   --* new
               ...
   ----------=----------=----------=----------=----------

   After making this change, please try for instance:

   ----------=----------=----------=----------=----------
   include misc.e

   pretty_print(1, {100, "Test", {"AB", "Huhu"}}, {4})
   puts(1, "\n")
   pretty_print(1, {100, "Test", {65, 66, "Huhu"}}, {4})
   puts(1, "\n")
   pretty_print(1, {100, "Test", {65, 66, 67}}, {4})
   ----------=----------=----------=----------=----------


5) Documentation of sort():
   Nothing special with version 2.4, I just came across it.
   I think it would be valuable to mention, whether or not the sorting
   of sort() is stable, along with a short explanation for beginners,
   what that means.


Thanks again for keeping up the good work with Euphoria!

Best regards,
   Juergen
