SAS enthusiasts,
Is there a way to extract the result (value=CHAR/NUMERIC) of the &datatyp
macro into a variable that is available to the data step that is attempting
to execute the macro? For instance, following the call to the macro I would
code a statement like IF whatever = 'CHAR' THEN DELETE;. The test below
appears to show that at least it is evaluating the data as I expected but I
can't seem to find a way to get the values CHAR or NUMERIC into a variable
that I can reference. I've tried numerous variations and have gotten it to
generate a VARIABLE named CHAR but not a VALUE!
Thanks in advance for any help/hints

The MemberName "0000" is NUMERIC.
Error: The MemberName "000A" contains CHARs.
The MemberName "0002" is NUMERIC.
The MemberName "0003" is NUMERIC.
The MemberName "0005" is NUMERIC.
