Hi Paula-
In V8.2, if you want to delete a single entry, try the %SYMDEL routine.
Here's a little log snippet - notice that TEST1 is removed:
9 %let test1 = Here is Value 1;
10 %let test2 = And here is Value 2;
11 %put _global_;
GLOBAL TEST1 Here is Value 1
GLOBAL TEST2 And here is Value 2
12 %symdel test1;
13 %put _global_;
GLOBAL TEST2 And here is Value 2
It would be pretty simple to wrap this is a macro that removed all the
global macro variables and left you with only the automatic variables
remaining. Setting the "symbol table to it's default" may be a bit more
problematic if you've done anything that changes an automatic variable and
you want it reset to it's default.

Subject: Delete entries in Symbol table without exiting the SAS session
Dear SAS friends,
I know if I creat macro variables properly, in the Symbol table, I should
see all the values assigned to it by executing
%put _all_;
But I always have to exit the SAS session to reset the Symbol table to its
default. Or I can not even change one single entry. Does anyone know anyway
to remove a macro variable (user defined, I mean) without exiting the
session? Thanks.
