Well, that is what i would expect. . . If an environment is defined with some commands, only those commands should work.But BLING would only handle the commands that it knows otherwise it would blow out in some manner.

No it is not - it is the command processor which will process the commands which will be DSNREXX if you follow the documentation. You will get a RC=-3 if you put in an invalid environment.
