Toby, Chris and everyone who responded offline, thanks and very much appreciated!

On 9.2 the same code produces:

ERROR: There is no matching %IF statement for the %THEN. A dummy macro will be compiled. 214 %let x="F"; 215 %end; 216 %mend test; 217 %test ('B') - 180 WARNING: Apparent invocation of macro TEST not resolved. ERROR 180-322: Statement is not valid or it is used out of proper order.

While I agree that error checking is important, I thought that SAS always ensured that previous code would continue to work. This is the second such discrepancy with that rule I've seen this week. Proc import using Excel as the DBMS on 64 bit systems was the other.
