Re: Commands inside RPG (was RE: authority question....)

Ken, you make a very good point about the advantage of using QCMDEXC for
overrides.  Tom is arguing against overrides in the first place (preferable
whenever possible), but the reality is that they are used in a lot of
existing applications.


BTW, there's another unique characteristic to QCMDEXC in regards to
processing overrides.  Unlike other programs or procedures, using QCMDEXC to
perform an override with "call level" scoping (*CALLLVL) will have the
override be effective for the caller of QCMDEXC.
