The following MSGPROC NCL procedure refers to an element in an MDO variable:
zex1007n: PROCEDURE
/* MSGPROC procedure to analyze elements */
DO FOREVER
MSGREAD VARS=&word*
IF &word1 = "TEST" THEN DO
SAY "&$MSG.MSGATTR is "&$msg.msgattr
SAY "&$MSG.MSGATTR. is "&$msg.msgattr.
MSGCONT
END
ELSE
MSGCONT
END
END zex1007n
After following the steps outlined earlier in this section to type this NCL procedure
and install it as your active MSGPROC procedure, execute the ZEX1002N NCL
procedure to send a message to your OCS window. The following screen shows the
results of executing ZEX1002N with MSGPROC active:
