I try to submit job, and all is good, when i hard coding. But I want to use params.
//REPORTS EXEC PGM=IKJEFT01,**PARM='SDSFINFO FTPSRV01 * hiqual'**
//SYSEXEC DD DSN=rexx.is.here,DISP=(SHR,PASS)
//SYSTSPRT DD SYSOUT=A,HOLD=YES
//SYSTSIN DD DUMMY
I write my JCL as Procedure. Is it real to describe parameters in the procedure invoice ? Like this:
//stepxx exec myproc,hiqual=hiqual,owner=*...
There are two kinds of procedure, cataloged procedure and in-stream procedure.
A cataloged procedure is stored in a library member separate from the execution JCL. This separate library is located by the system searching through a list of such libraries defined to it in SYS1.PARMLIB. This list can be overridden with the JCLLIB statement in the execution JCL. Your shop likely has a standard location where cataloged procedures are stored.
In-stream procedures are located in the same library member as your execution JCL. The PROC statement must be between your jobcard and the EXEC statement that executes the named proc. The in-stream procedure must end with a PEND statement.
It is common to use symbolic parameters with procedures, making them more flexible.
You're headed in the right direction...
[jobcard is here]
//MYPROC PROC
//REPORTS EXEC PGM=IKJEFT01,PARM='SDSFINFO FTPSRV01 &OWNER &HIQUAL'
//SYSEXEC DD DSN=[rexx.is.here],DISP=(SHR,PASS)
//SYSTSPRT DD SYSOUT=A,HOLD=YES
//SYSTSIN DD DUMMY
// PEND
//*
//MYSTEP EXEC PROC=MYPROC,HIQUAL=ABC,OWNER=XYZ
...where the stuff in square brackets must be supplied by you. This will result in MYPROC being executed as if you had hardcoded...
//REPORTS EXEC PGM=IKJEFT01,PARM='SDSFINFO FTPSRV01 XYZ ABC'
//SYSEXEC DD DSN=[rexx.is.here],DISP=(SHR,PASS)
//SYSTSPRT DD SYSOUT=A,HOLD=YES
//SYSTSIN DD DUMMY
Sometimes procs are coded with default values for symbolic parameters...
//MYPROC PROC ENV='PROD'
//REPORTS EXEC PGM=IKJEFT01,PARM='SDSFINFO FTPSRV01 &OWNER &HIQUAL'
//SYSEXEC DD DSN=&ENV..REXX,DISP=(SHR,PASS)
//SYSTSPRT DD SYSOUT=A,HOLD=YES
//SYSTSIN DD DUMMY
...and sometimes the default value is documentation...
//MYPROC PROC ENV='SPECIFY_PROD_OR_TEST_OR_QA'
//REPORTS EXEC PGM=IKJEFT01,PARM='SDSFINFO FTPSRV01 &OWNER &HIQUAL'
//SYSEXEC DD DSN=&ENV..REXX,DISP=(SHR,PASS)
//SYSTSPRT DD SYSOUT=A,HOLD=YES
//SYSTSIN DD DUMMY
...forcing the execution JCL to provide a value or suffer a JCL error at run time.
Note that with the SET statement you can use symbolic parameters without needing a procedure, cataloged or in-stream. This...

// SET HIQUAL=ABC
// SET OWNER=XYZ
//*
//REPORTS EXEC PGM=IKJEFT01,PARM='SDSFINFO FTPSRV01 &OWNER &HIQUAL'
//SYSEXEC DD DSN=[rexx.is.here],DISP=(SHR,PASS)
//SYSTSPRT DD SYSOUT=A,HOLD=YES
//SYSTSIN DD DUMMY
//*
...will give the same results as the first example, without using a proc.
There are usually shop standards to which you will be expected to adhere. Often mainframe shops have a dedicated group whose function is to run production job streams, scheduling hundreds or thousands of such job streams per day.
