Re: Global variables in a Service Program

Nathan,

 That's an interesting idea. Would you mind posting a short code sample so
we can see it in context?

JK

I sometimes create service programs with nothing more than exported data
structures, so they can be bound to other programs and service programs in
the same activation group, and share the same data.

Subject: Global variables in a Service Program

Quick question.  I've got some variables and constants that I'd like to
make global but I'm concerned about scope.  Basically, I have three
service programs that all use a couple of the same fields, i.e. errMsg,
cmdLen, myCmd, etc..  Do I put them at the top of each svcpgm module or in
a separate copybook?  And would there be issues with duplicates when all 3
svcpgms were bound into one rpgle pgm?

Thanks,
