Well there you go: //MASK EXEC PGM=IEFBR14 //STEPLIB DD DISP=SHR,DSN=some.dataset.name
Looked before, DOLR was 8/1; repeated to be sure looking at DOLR didn't change DOLR (which would be Bad, but); ran job; now DOLR is 8/5. Now, OP had something about "the files are large" but if anyone explained why that mattered for this, I missed it.
