Thanks Hank, I appreciate the pointers to possible locations for the UNIT specification. However, since pre-allocating the file solved my immediate (and very short-term) issue, I am not pursuing this any further.

Been too long but the UNIT is either from the ISPF configuration table OR TSO segment. I suspect the former judging from a ISPVCALL trace. You could use ISPCCONF to build your own ISPF config module and TSOLIB/STEPLIB to it but If you don't have even that much control over your environment you'll need to annoy the sysprogs to get a change made.

Gil, The problem here was that the allocation is "under the covers" somewhere in the LMDLIST service, and all I could see was the resulting allocation to the "WORKxx" storage pool. No LMDLIST parameters to affect the allocation method are mentioned in the FM. Pre-allocating the dataset before executing LMDLIST solved the problem.

SYSALLDA? Whatever. "Using Data Sets" mentions SYSDA only in examples; SYSALLDA not at all. JCL Ref. mentions SYSDA only in examples, and: SYSALLDA: IBM assigned group-names include SYSALLDA, which contains all direct access devices defined to the system. What does IBM recommend? (Perhaps in Init/Config/Admin?) Aren't there better ways of allocating temporary data sets than by relying on esoteric names? SMS guidelines?
