Subject: Re: Stored Compiled macros, multiple catalogs
Content-type: text/plain; format=flowed;
Thanks to Peter Crawford for his reply to my query on multiple catalogs for
stored compiled macros.
Reiterating the problem: in an object oriented environment we wanted to
have multiple catalogs containing stored compiled macros according to their
subject area.
Conceptually, since SAS supports concatenated library references, you could
start a session with the SASMSTORE option pointing to such a reference. It
doesn't work, for reasons that should have been obvious when it was first
conceived. A stored compiled catalog has the SAS file name of SASMACR. The
read process for SAS using concatenated references finds the first
occurrence of each SAS file name for each Member type.
Therefore, only the first SASMACR catalog will be found and the SAS System
will search only that file for the entry name associated with that macro
call. If it is not found it will NOT then search for any more SASMACR
catalogs before reporting that the macro reference is not resolved.
There is no immediately obvious solution for catalog concatenation unless a
single composite catalog is created. For our site this means even more
austere naming since the first character will need to reference a subject
area for the source code, and the description include up to 8 characters for
a catalog subject name.
Much as I really dislike hanging my hopes on future unseen untested
releases, it seems I must wait on version 8 for 40 character entry names.
Thanks again Peter, you've saved me wasting too much time on this.
On a related issue, has anyone found a way to clear the SASMSTORE related
library reference? Issuing an OPTIONS statements will let you changed the
SASMSTORE library reference from FRED to GINGER. GINGER will then be
searched for macros and not FRED, but FRED is still flagged as being in use
and can't be cleared or reassigned. Looks like a :feature: to me.
