This course is essential for all those working in technical roles within a z/OS environment. The course teaches the coding of job control statements to execute programs and access datasets and how to write and test catalogued procedures.<br><br>The course combines classroom tuition with practical exercises using various IBM utilities.<br>This definitive JCL course is regularly upgraded to reflect recent developments in z/OS. The practical sessions of this course now comprise almost 40% of the course timetable!<br><br>This course is also available for one-company, on-site presentations and for live presentation over the Internet, via the Virtual Classroom Environment service.

The ability to use TSO/ISPF and a basic knowledge of z/OS and its file structure.

  • state the purpose of each z/OS job control statement
  • code JCL statements to access disk and cartridge files
  • describe and use the commonly used parameters
  • correct syntax errors in JCL statements
  • code in-stream procedures and override, nullify and add parameters
  • appreciate the implications of SMS when using z/OS JCL.
