-----Question-----
The program I'm look at is call a program and then passing a parm.  
Call PGM(*libl/css) Parm(&BDATE &TDATE)
I entere for the date parm 20060131 20061231  what am I doing wrong.
-----Answer-----
The chances are good that the program expects the dates to be in YYMMDD format. Try using:

CALL CSS PARM('013106' '123106')

Answer
Call PGM(*libl/css) Parm(&BDATE &TDATE)

If this is a line in a CL program, &BDATE and &TDATE represent variables.  The program you are calling (CSS) must be prepared to receive two variables, defined like &BDATE and &TDATE. (If &BDATE and &TDATE are character fields, the parameters in the called program must also be character variables of the same length).

In a typical example of a CL program calling an RPG program, the CL program would look like:

CSSCL:    PGM  PARM(&BDATE &TDATE)
         DCL &BDATE *CHAR 6
         DCL &TDATE *CHAR 6

         CALL PGM(*LIBL/CSS) PARM &BDATE &TDATE)

END:      ENDPGM

The calculation section of the RPG program would begin with


         *ENTRY    PLIST
         PARM          BDATE 6
         PARM          TDATE 6


You would compile the CL program and the RPG program using the CRTCLPGM and CRTRPGPGM commands, then call them:

  CALL CSSCL PARM('010106' '123106')

I hope that helps!
