I didn't see anything in this thread about WHY you want to do this, but you seem to have ruled out the simpler, safer techniques. I hate to say it, but if you have to ask for a more sophisticated approach, you probably should not even try it.
We ran a superbly (RYO) written load module trace application for several years. It gathered lots of data without the expense of an ISV product. It even worked in 64-bit mode until we converted the first system that had more than 2 GB of storage--at which point the entire system died a wretched, agonizing death. Whoever is inducing you down this path needs to be talked out of it. . .

Instead I would like my module to get control. This module can then perform certain tasks before passing control to the user requested processing module. Here as a simple flow: - User calls module "A" - My module "B" gets control instead (without the user noticing this) - After internal processing "B" calls "A" Is there a way to achieve this using documented interfaces (or otherwise)? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
