This course teaches:

  • how to code JCL (Job Control Language) statements to obtain a correct execution of programs and the correct treatment of data sets;
  • the interpretation of job output via SDSF (Spool Display and Search Facility) in order to correct possible errors as soon as possible;
  • the use and creation of procedures.


No public sessions are currently scheduled. We will be pleased to set up an on-site course or to schedule an extra public session (in case of a sufficient number of candidates). Interested? Please contact ABIS.

Intended for

Programmers, operators, system programmers, schedulers.


Basic knowledge of ISPF/PDF is necessary (see course ISPF/PDF basics). You can test yourself to see if you have enough background by printing and filling in the self-test ( PDF file - 26 KB).

  • The different statements and their function:
  • JOB statement: accounting information, job scheduling parameters, execution parameters, job output specification
  • EXEC statement: PGM, PROC, PARM, COND, TIME, etc.
  • DD statement: data set description, resource specification, output description, in-stream data sets, etc.
  • IF-THEN-ELSE construction
  • OUTPUT statement
  • Job log and job output • SDSF manipulation
  • Special datasets and associated parameters:

concatenation • partitioned and sequential data sets • temporary data sets • backward references • GDG • SMS parameters • JOBLIB • STEPLIB • ...

  • Use of procedures:

definition • parameters • changing and adding • symbolic parameters

  • Debugging of JCL, frequent abends, ...
  • JES2 control statements

Training method

About half of the time is spent on practical exercises.

prima; goede basiscursus/opfriscursus

  (, )

stof is aardig ingewikkdeld (JCL) en vergt enige ervaring. Ik heb de basis meegekregen en zal deze in de praktijk uit moeten breiden

Prima; mijn doel was gestructureerd inzicht in de opbouw van JCL te krijgen en de betekenis van de verschillende onderdelen te verduidelijken zodat ik beter weet waarmee ik bezig ben. Volgens mij is dat goed gelukt.
