Prior to the use of APIs, a very simple one liner is to attempt to
open a workstation display file (any one will do) and check the
error indicator for failure since display files cannot be opened in
batch.

AFaIK a job running in batch may still be able to open a Display device file. Whether it is possible depends on the DEV parameter in effect for the OPEN [from the *FILE or the Override], and whether the device(s) is available [to the batch job]. I believe only a DSPF with DEV(*REQUESTER) [and not impacted by an OVRDSPF DEV(named)] can be presumed to fail as described.
