Laura, One concise, complete method is: DATA NEW; SET OLD; ARRAY _NUM _NUMERIC_; ARRAY _CHAR _CHARACTER_; DO PTR=1 TO DIM(_NUM); IF _NUM(PTR) EQ -9 THEN _NUM(PTR) = .; END; DO PTR=1 TO DIM(_CHAR); IF _CHAR(PTR) EQ '-9' THEN _CHAR(PTR)=''; END; RUN; This will run in 6.08 under MVS (or is it OS/390 now?).

Sent by:Laura C Schmidt <lschmidt+@PITT.EDU> Hello, everyone. I know this is a very silly question, but I am in the process of converting to SAS for unix and I have a deadline to meet. I have about 300 variables that use the code -9 for missing, so I would like to find one simple command in which I can list the variables and state that -9 should be treated like system missing (similar to the 'missing values varname (-9)' command in SPSSPC). I have checked various SAS books but I can not see it right now. Can someone e-mail me this, and maybe some other simple commands for unix if you have a sample file handy?

Thanks to all, Laura C. Schmidt University of Pittsburgh
