Look toward the back of the Macro manual -- there's a macro called %SYMCHECK
-- it may also be in the SAS System autocalls library.  If not, copy it from
the manual *exactly* (extra whitespace inside the quoting and resolving
functions *will* effect the function of the macro).
 
You can also (v. 6.11 and up) check in one of the new DICTIONARY/SASHELP
tables (I believe 'MACRO').
