Subject:      Delete a temp macro inside another macro (Was Re: Macro,
              only for the sake of modular programming?
Comments: To: Ron Fehd <rjf2@CDC.GOV>

Hi there,

First of all, I would like to thank everyone who responded my previous
post "Macro, only for the sake of modular programming?", your comments
are all very helpful.

Now I have a new question. Not sure if this is a good idea. I want to
define a small macro 'in' inside another macro 'out'. 'in' will be called
multiple times inside 'out', at the end of the macro 'out', I use proc
catalog to delete the macro entry 'in'. It seems to work fine, except
that there is a note "NOTE: Statements not processed because of errors
noted above.". I'm not sure what does it mean.

Any comments?

Thanks

Ya
