A JCL can be made of many job steps, and a job step can execute a program directly, or it can call a procedure. Thus, JCL can execute one or more programs (job steps).
The statement, which contains the job step program information, is called the EXEC statement.
The motive of the EXEC statement is to provide the required information. This information is forwarded to the program that executes in the job step.
Syntax
The basic syntax of a JCL EXEC statement is as follows.
//Step-name EXEC Positional-param, Keyword-param
