use of curdate within MVS - should it work?

[Steve Rogers <srogers@KBTOYS.COM>]

We are in the process of converting  AS-400 version 7.5 of PeopleSoft HRMS to
MVS.  While testing an SQR containing the following code -

     FROM PS_JOBCODE_TBL  JC
     WHERE JC.SETID = SETID                           !
     AND JC.JOBCODE like 'K%'
     AND JC.EFFDT = (SELECT MAX(JC1.EFFDT)
                     FROM PS_JOBCODE_TBL JC1
                         WHERE JC1.JOBCODE = JC.JOBCODE
                         AND JC1.EFFDT <= curdate() )
          AND JC.EFF_STATUS = 'A'

     I received an error that indicated that MVS could not handle curdate.  Here
is the error

(SQR 5528) DB2 SQL PREPARE/DECLARE error -440 in cursor 5:
    DSNT408I SQLCODE = -440, ERROR:  NO FUNCTION BY THE NAME CURDATE HAVING

    DSNT416I SQLERRD    = X'FFFFFF9C'  X'00000000'  X'00000000'  X'FFFFFFFF'  X'
             INFORMATION

     Can anyone tell me why this is happening and how to resolve it?

     thanks,
     Steve
