Tim,
I'm surprised at your comments on the RUN and QUIT statements. In
several procs, including datasets, the use of a RUN statement will cause
the current command (in this case the Modify) to execute. This can then
be followed by another command without re-entering the PROC statement.
So the use of the 'new' QUIT statement simply tells SAS to end the
procedure.
If anything, the use of RUN to terminate a step is something of an
oddity, although, of course, those of us who've been using SAS for years
have grown accustomed to it. The current usage is more consistent, not
less, as we use RUN to do just that - cause something to run, and QUIT
to terminate a step where this is not implicit in the act of running it
(as it is in a data step etc.) .
In some cases, of course, statements are automatically executed (is this
just in SQL? ), so it is the RUN statement which is redundant therein,
and _only_ the QUIT statement has any effect.
