Marc,
Jan's advice is good. You can use cval('version') to get the long character
string, but then it would not be good to use ">=" because you would be
comparing text strings, not version numbers. Some version names have strings
like 'eXtreme' in them, and some have 'for Windows' in them. The alphabetical
order represented by ">=" won't serve you well.
You can use cval('build') or cval('version build') to get a string of the
numeric version build. Sorry, I don't have a way any more to see what kinds of
values get returned by 7.5 or 7.6, but it should be easy to test.
When I upgraded an installation from 7.6 to 8.0, I put this in an RBASE.DAT
file, to be sure that if anybody accidentally found or started the obsolete
version of R:BASE, they got scolded properly, and the application continued
only if the proper version was running.
------------------------------------
SET VAR vVersion = (cval('version'))
IF vVersion CONTAINS 'v8.' THEN
ENDIF
IF vVersion CONTAINS 'v7.' THEN
PAUSE 2 USING 'R:BASE 7.6 is offline. Please use R:BASE V-8'
EXIT
ENDIF
------------------------------------
Whatever you do for a test, anticipate that version build numbers change
frequently, and be sure your code will stop or continue, (whichever is
appropriate), the day that you install eXtreme 9.0 (32) or eXtreme 9.0(64).

Hi
Is there a way to do
IF (CVAL('VERSION')) >= 7.6 THEN
or
IF (CVAL('BUILD')) >= ???? THEN
I only want offices using 7.6 to run a file and I do not want the 7.5 users
to be able to run this file.
Thanks
Marc
