Hello,

When you start up IDL it will print version info...

[Sei:~] Ben% idl
IDL Version 6.3, Mac OS X (darwin ppc m32). (c) 2006, Research
Systems, Inc.
Installation number: 99906.
Licensed for personal use by Michael Sieracki only.
All other use is strictly prohibited.

To get the version programmatically you can access the "release" tag
of the !version system variable.

IDL> help, !version,/str
** Structure !VERSION, 8 tags, length=76, data length=76:
ARCH STRING 'ppc'
OS STRING 'darwin'
OS_FAMILY STRING 'unix'
OS_NAME STRING 'Mac OS X'
RELEASE STRING '6.3'
BUILD_DATE STRING 'Mar 23 2006'
MEMORY_BITS INT 32
FILE_OFFSET_BITS
INT 64

You'll see programmers doing stuff like...

IDL> if (!version.release LT 7) then print, "old duffer"
old duffer

IDL's string-to-float conversion seems to handle the oddball release
format you might see...

IDL> if ('7.0.4' LT 7.0) then print, "old duffer"

Cheers,
Ben
