Retrieve Progress/OE version number

[D.Cook]

Anyone know how to retrieve the Progress/OpenEdge version number? I was hoping to find a pre-processor name, but the best option I can find is parsing the 'version' file in the DLC directory.
I seem to recall there might be some undocumented pre-processor names.

Oh, seems I need to think a bit harder before I post.
Found the keyword PROVERSION.

While I'm here, here's a code sample for checking if the current version of Progress is high enough (where {1} is the required version):

if (if index(proversion, ".") eq 2 then "0" else "") + proversion lt "{1}" then
do:
   message "Cannot execute: Progress OpenEdge {1} or higher is required." view-as alert-box error.
   return.
end.

If you need to make the check at compile time you can do something like this:

&IF DECIMAL(SUBSTRING(PROVERSION,1,INDEX(PROVERSION,".") + 1)) >= 9.0
&THEN
/* conditional code goes here... */
&ENDIF

Thanks Tom, didn't realise you could use the PROVERSION function at compile time.
