PC SAS 6.11
 
PROBLEM:
 
Every time I run my program (macro intensive) and encounter a problem
(within a macro code) I need to restart my SAS session (annoying and
time consuming).  If I don't, then when I correct the problem rerun
within the same SAS sessioin I receive the same error message.  This
leads me to believe that SAS reuses macros in WORK library without
refreshing them.
 
I have used following code to clean up the WORK library.
 
  PROC DATASETS LIBRARY = WORK KILL;
 
But this code does not remove macro catalog called "SASMACR" in WORK
library, so same errors reappear unless I restart my SAS session.
 
I have used "PROC CATALOG CAT=WORK.SASMACR KILL" and it does remove
all macros defined within SASMACR catalog.  However, when I rerun my
program within the same SAS session, SAS gives me an error "Apparent
invocation of macro not resolved" for some macros (not all).
 
HELP ON:
 
Is there a way to remove and recreate WORK library within SAS
session?
Is there a command to refresh files in WORK library?
Any solutions?
 
Thank you very much.
