One handy feature of the LDA is that it is copied to a submitted job. By that I mean that when job A submits job B, the LDA in job B is a duplicate and separate copy of job A's LDA. At this point job B can change the LDA without effecting job A's LDA.
Warning: Some systems use the LDA to submit parms to a called program. We find this to be unreliable.
Read again what WoodEngineer wrote. Each job have its own LDA, JobA is with LDA-A and JobB is with LDA-B, which is a copy of the LDA-A if jobB was called by JobA
If you need a second data area for a job and want to keep it unique so it cannot be used by others, here is my suggestion. Create one in QTEMP. IT will remain active for the job running and will disappear when the job completes. This way there is no maintenance or cleanup.
