Using the &PARM Symbolic

The CAISDI/els Interface Controller allows the use of a special symbolic parameter that is named &PARM. In any control statement or comment, you can embed the &PARM symbolic parameter. For example:

//ENABLE   JOB  '1234','Systems',CLASS=A
//CASDIELS EXEC PGM=CSDECNTL,PARM='ca-1'
//STEPLIB  DD  DSN=CAI.CAW0LIB,DISP=SHR    
//SYSPRINT DD  SYSOUT=*    
//REPORT   DD  SYSOUT=*
//SYSIN    DD  *
ENABLE PRODUCT=&PARM

The value of the PARM= for the JCL EXEC statement sets the value of the &PARM symbolic to “CA-1”. The control statement “ENABLE PRODUCT=&PARM” is interpreted as if you had specified “ENABLE PRODUCT=CA-1” yourself. z/OS allows up to 100 characters to be passed through the PARM= parameter. Internally, the length of the control statement including the substitution of the &PARM value must not exceed 200 characters.
