No way that i'm aware of. Once the job is already running it is too late to self-modify. . .I can write out a dataset or into a pds member but how can i access it in the same job?
If i understand the question, no, the values will not yet be resolved. They can no longer be changed, but they have not been resolved by the system.So if they JCL is submitted but is in postion 3 before it is ran is the values already resolved?
