Subject: Mea Culpa: RESOLVE Will Return Values in a Macro
Content-Type: text/plain
As Keith points out, with correct quoting one can embed macro invocations in
a datastep and have the macro resolve separately for each observation. This
is scary--I do not know v6 yet, and we will go to v8 in less than a century.
