Normally, service program are written to run in *CALLER. This is not a
requirement, but the benefit is you can export fields from the service program
and import them into the calling RPG IV programs. If the service program is in a
different activation group, then you cannot do this export/import.
If you have two or more program's running in different activation groups, the
data imported by one, cannot be passed to the other.
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.
This is one reason I switched RPG xTools' CGILIB (similar to CGIDEV2) to use
pointers to user space objects instead of dynamic memory allocations. Once I
eliminated all the ALLOC's from my programs, I had zero issues with situations
like this.
To solve your problem, make sure you copy and data you want to pass as a
parameter, to a global field that is declared in the caller's program. Don't
pass the "return value" from a call to a CGIDEV2 function. (Which is what I
suspect you are doing).

Subject: CGI and activation groups

I am working on a CGI program that calls other programs based off
selection.

I am OK calling the other programs as long as they exist in the same
activation group.  

When I try to call a program that exists in a different activation group
I get the following messages.

Space offset X'0006A769' or X'0000000000000000' is outside current limit

  for object BUCKLEDEV QTMHHTTP  031721.

RPG status 00222 caused procedure ZHBGETINPU in program
CGIDEV2/CGISRVPGM2
  to stop.


I assume the ZHBGETINPUT cannot see the original browser input because
it is in the other activation group.

Any help would be appreciated.

Thanks in advance.
