The Datacom console command "MESSAGE DD@MSG,DB00148" gets the following error message:
DB00605E - CONSOLE BAD CONTEXT - MESSAGE DD@MSG,DB00148
no matter how it's executed (MVS Modify command or via DBUTLTY COMM OPTION=CONSOLE).
Release : 15.1
Component : Datacom/AD
In order to use that console command, the DD@MSG SYSOUT dataset must be already allocated to MUF.
However, this sysout is allocated ONLY if there is at least a:
MESSAGE DD@MSG,DBnnnnn
card in the SYSIN deck when the MUF starts.
