Chapter 45: Defining JCL Statements
JCL (Job Control Language) statements control the flow of a complete job. They determine which programs run, the sequence in which each program runs, and which files are accessed, copied, or created.
Remote job entry (RJE) facilities use JCL statements to control jobs running on remote computers, such as a 3090 mainframe or an IBM System/38.

Instructions: Follow these steps to add a JCL statement:
1. Enter B (for "before") or A (for "after") in the B/A (Before/After) field to indicate whether the statement is executed during signon or the job itself or is executed during signoff.
2. Enter a number in the Sq (Sequence number) field to identify when the statement executes. Hint: We recommend that you add 10 to each sequence number so you can insert a new statement between existing statements easily without having to renumber other statements.
3. You advance to the JCL statement field. Enter the statement.
