Simple CLIST to Run a COBOL Program

PROC 0
    SUBMIT 'MYCOBOL' DATASET('MY.INPUT.FILE') OUTDATASET('MY.OUTPUT.FILE')
    IF RC = 0 THEN
        WRITE 'COBOL program completed successfully'
    ELSE
        WRITE 'COBOL program failed'
    ENDIF
END

Submit a COBOL program using TSO/ISPF batch environment via CLIST.

Let’s Try →

CLIST Conditional Execution

PROC 0
    SUBMIT 'PROG1'
    IF RC = 0 THEN
        SUBMIT 'PROG2'
    ELSE
        WRITE 'Step 1 failed, skipping Step 2'
    ENDIF
END

Run a second program only if the first program completes successfully.

Let’s Try →

CLIST Allocate Temporary Dataset

PROC 0
    ALLOC FI(TEMPDS) DA('&&TEMP.DATA') NEW SPACE(5,1) RECFM(FB) LRECL(80)
    IF RC = 0 THEN
        WRITE 'Temporary dataset allocated'
    ENDIF
END

Allocate a temporary dataset for processing within CLIST.

Let’s Try →

CLIST Multi-Step Batch Job

PROC 0
    SUBMIT 'PROG1'
    SUBMIT 'PROG2'
    SUBMIT 'PROG3'
    WRITE 'All steps executed'
END

Run multiple programs sequentially in a single CLIST.

Let’s Try →

CLIST Pass Parameters to Program

PROC 0
    SET PARAM1='INPUT1'
    SET PARAM2='OUTPUT1'
    SUBMIT 'MYPROG' PARM(&PARAM1 &PARAM2)
END

Pass command-line parameters to a program using PARM keyword.

Let’s Try →

CLIST Execute DB2 Program

PROC 0
    SUBMIT 'MYDB2PGM' REGION(4M)
    IF RC = 0 THEN
        WRITE 'DB2 program ran successfully'
    ELSE
        WRITE 'DB2 program failed'
    ENDIF
END

Run a DB2 program with DB2 precompiler environment using CLIST.

Let’s Try →

CLIST Redirect Output

PROC 0
    SUBMIT 'PROG1' OUTDATASET('PROG1.OUT')
    SUBMIT 'PROG2' OUTDATASET('PROG2.OUT')
    WRITE 'Output directed to separate datasets'
END

Direct output of different programs to different datasets or SYSOUT classes.

Let’s Try →

CLIST Retry Step on Failure

PROC 0
    SUBMIT 'PROG1'
    IF RC > 0 THEN
        WRITE 'Retrying Step'
        SUBMIT 'PROG1'
    ENDIF
END

Automatically re-run a program if it fails.

Let’s Try →

CLIST Read and Process File

PROC 0
    ALLOC FI(INFILE) DA('MY.INPUT.FILE') SHR
    DO WHILE NOT EOF(INFILE)
        READ INFILE INTO LINE
        WRITE LINE
    ENDDO
    FREE FI(INFILE)
END

Read lines from a dataset and display them sequentially.

Let’s Try →

CLIST Submit Another Job

PROC 0
    SUBMIT 'USER.TEST.JOB'
    IF RC = 0 THEN
        WRITE 'Submitted job successfully'
    ELSE
        WRITE 'Job submission failed'
    ENDIF
END

Trigger another job from this CLIST program using SUBMIT command.

Frequently Asked Questions about Tso-ispf-scripting

What is Tso-ispf-scripting?

What are the primary use cases for Tso-ispf-scripting?

Automating dataset and member creation, deletion, and modification. Submitting and monitoring batch jobs (JCL). Building ISPF panels for custom workflows. Data extraction and reporting from mainframe datasets. Automating repetitive TSO/ISPF operations using REXX or CLIST

What are the strengths of Tso-ispf-scripting?

Reduces repetitive mainframe operations. Standardized panel interface for end-users. High integration with z/OS datasets and jobs. Stable and mature platform in enterprise mainframes. Supports rapid automation of routine tasks

What are the limitations of Tso-ispf-scripting?

Limited to IBM mainframe environment. Outdated interface for modern GUI/UX expectations. Steep learning curve for non-mainframe users. Debugging complex scripts can be challenging. Integration with non-mainframe systems is limited

How can I practice Tso-ispf-scripting typing speed?

CodeSpeedTest offers 10+ real Tso-ispf-scripting code examples for typing practice. You can measure your WPM, track accuracy, and improve your coding speed with guided exercises.
