Re: I think I've asked before: easy way for ILE RPG program to know whether it's running in a batch job or an interactive job?

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.
