Except that I looked up the API and it doesn't seem to have anything to do with retrieving the Local Data Area!

But yes: Unless you are wanting to retrieve the LDA (etc) of another job (other than the current job that the MI program runs in), an API would be a better choice, probably. Much easier! And guaranteed to work from release to release, which is probably the best argument. No more messing with System State programs!

Couple of things, code 9 returned doesn't prove that all 30 tables were traversed. You can also exit on a null value with code 9 which just presumes that there are no more tables left to search. Also the job active check is after the LDA check which really makes no sense. The other thing is that have you verified the inputs into the program, that the job you're searching actually does exist? I know it seems trivial but....

Finally this code is dead after V5R4. You may want to abandon this code and use the api as suggested.
