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.

Bruce
