MVS/ESA JCL and Utilities (DEV1120)
Course Description
This is the course that deals with JCL in depth and gives the student ample opportunity to write and correct JCL jobstreams. It covers all of the JCL statements, procedures and some IBM utility programs. Lecture is interspersed with many exercises that have the student practice the use of JCL parameters covered in class. In addition, there are hands-on workshops including one that requires the creation of a jobstream using several of the utilities.
JCL is not an easy topic, but students generally feel they have a good grasp of the material after this course. The aim is to make it palatable and therefore understandable.
