An alternative question: Is there any way to record all function calls made by a function / procedure / script? I could put something like: help,/trace,output=temp printf,tracking_file,temp[0] in every file in my project in principle, but I think that's a bad thing to do on many levels. Is there a modified version of 'journal' or 'errorlogger' that can do what I want? I have in mind making my own .dot files to process with graphviz, which would be straightforward enough if I could get components of the trace printed out automatically.

I ended up writing a python wrapper that concatenates a bunch of IDL code into a single file, appending a logging call to each. It's moderately flexible, in case anyone is interested in trying it: http://code.google.com/p/..._pipeline_and_log.py
