it seems that some changes were made to the %sysfunc function in SAS9.2.

same code will work on sas9.1, but not on 9.2 phase2 windows XP.

261  /*SAS9.2*/
262  %put NOTE: HEX FFF=%SYSEVALF(FFFX);
ERROR: A character operand was found in the %EVAL function or %IF condition
where a numeric
       operand is required. The condition was: FFFX
NOTE: HEX FFF=
263
264  %put NOTE: HEX FFF=%SYSEVALF(A000X);
ERROR: A character operand was found in the %EVAL function or %IF condition
where a numeric
       operand is required. The condition was: A000X
NOTE: HEX FFF=


9    /*SAS9.1*/
10   %put NOTE: HEX FFF=%SYSEVALF(FFFX);
NOTE: HEX FFF=4095
11
12   %put NOTE: HEX FFF=%SYSEVALF(A000X);
NOTE: HEX FFF=40960
