skill to detect IC5

This is what I've used for the last 17 years:

(procedure (abGetVersionNumber)
  (let ((parsed (parseString (getVersion))))
       /* in 4.4 onwards, version string is slightly different */
       (if (equal (caddr parsed) "version")
           (cadddr parsed)
           (caddr parsed)
           )))

The other thing you might use (if it's database related) is dbGetDatabaseType() - that will tell you if you're running in a CDB (it returns "CDBA") or OpenAccess (it returns "OpenAccess") enabled version of the tool.

Hi Andrew - that does work but it returns alot of info, I only need to know if its IC5 or 6.  I did finally find 2 other solutions.   The if does not work and looks like its missing a  close ) but it does not go where I thought it should.

if( rexMatchp("6.1" getVersion() then
   icVersion="61"
else
   icVersion="51"
) ;if

You can also make use of the database format. E.g.

case( dbGetDatabaseType()
   ("CDBA" icVersion="51")
   ("OpenAccess" icVersion="61")
) ;case

What do you mean it returns a lot of info? In IC5141, it returns "5.1.0" and in IC615 it returns "6.1.5" (6.1.4 returns "6.1.4"). That doesn't sound like a "lot of info". You could check if it's "5.1.0" and anything else could be assumed to be IC61 (assuming you're not running really old versions):

inIC5141=(abGetVersionNumber()=="5.1.0")

Then you have a flag to say whether you're in IC5141 and you can do:

if(inIC5141 then
  ; do IC5141 related stuff
else
  ; do IC61 related stuff
)

In the first example you've posted, the missing parenthesis is before the then:

if( rexMatchp("6.1" getVersion()) then
  icVersion="61"
else
  icVersion="51"
)

Fairly obvious if you look up rexMatchp in the documentation that it's a function accepting two arguments.
