It sounds like a version control problem. I concur with other members of
this group that CVS works very well for version control of IDL source
code. If you use CVS or any other tool that supports RCS tags, you can
simply embed an RCS tag (such as $Id$) in an IDL string variable:

rcs_id = '$Id: imdisp.pro,v 1.45 2000/08/28 16:17:14 gumley Exp $'

The procedure or function can then print or save the string variable to
a file when it is called, and CVS takes care of inserting the version
number, date, and owner of the last modification.

For more CVS information, see
