Execution of program

All programs to be executed must reside in a library, which is a partitioned data set (PDS) or partitioned data set extended (PDSE). The installation should maintain a list of programs available in its libraries. Libraries are of three types:

System libraries: such as SYS1.LINKLIB
Private libraries: specified in a JOBLIB or STEPLIB DD statement
Temporary libraries: created in a previous step of the job.

For information about libraries, see Resource control of program library.

Execute a program in a system or private library by coding:

  
//stepname  EXEC  PGM=program-name

Execute a program in a temporary library by coding:

  
//stepname  EXEC  PGM=*.stepname.ddname  
//stepname  EXEC  PGM=*.stepname.procstepname.ddname

Examples:

  
//ST1    EXEC  PGM=MYPROG  
//DSPROG DD    DSNAME=PDS1(MEMP),DISP=SHR  
//ST2    EXEC  PGM=*.ST1.DSPROG
