Form CHECK_SYSTEM
Check users workstation is running
WINDOWS 95, or WINDOWS NT.
OS/2 uses 8.3 file names which are no good for
this application as filenames created are 30 char
same as table name.
You could change the logic to only use the first 8 chars
of the table name for the filename, but you could possibly
get problems if users had exported already with a table
with the same first 8 chars.
As an alternate method you could request the user to input
the full path including filename and remove the logic to
build the path using the table name.
