Had the following on a customer's machine:

Date: 12/07/2012    Time: 14:27:23                                             
Program error at 'scratchpad.4gl', line number 0.                               
FORMS statement error number -6208.                                             
Module 'scratchpad': already loaded.

Eventually I recompiled all of the library functions and put the latest set on their box.

However it will be a big job to produce a set with exactly the same versions as they currently have, unless there is a quick way I don't know of identifying which ones have the module 'scratchpad' included?  Then I can just recompile those.

Is there a smart way to do this?

The .42m generally corresponds 1:1 with the .4gl source file.  You need to look in the .42r file.  It's a simple structure and you can write some C code to interpret it properly, but for most purposes (assuming you are on a *nix OS) you can just use strings(1) to get the names out of them.  E.g.

strings program.42r | grep scratchpad

If you want to be cleverer or the word scratchpad appears in too many function names, a quick and dirty script like this will work (slowly).  e.g.

genref -m *.42r | grep scratchpad.42m
