Re: CGI and activation groups

Likewise, if you use CGIDEV2, it uses dynamic memory allocations. So the data
allocated in one activation group is scoped to that activation group.
I'm not certain, but I believe because it is allocated in AG1 it cannot be
passed to a program in AG2. If you're passing a parameter to the second 
program
that was dynamically allocated or is based on a dynamic allocation--you're in
violation.

It works fine to pass a pointer allocated in AG1 to a program in AG2.

But the AG1 pointer would only be valid as long as AG1 was still
activated; the dynamic storage gets reclaimed along with the activation
group.  So if the AG2 program saved off the pointer, and actgrp AG1 got
reclaimed after that, then the AG2 program would not be able to access
that storage.
