START command processing when the member is a procedure

During START command processing, if the member specified does not start with a JOB statement, the system creates a JOB statement and EXEC statement that will invoke the procedure of the same name as the member.

For example, the member INIT exists in SYS1.PROCLIB as follows:

//IEFPROC   EXEC   PGM=IEFIIC

JES2 automatically issues the command S INIT.INIT,,,JES2,SUB=JES2 and the following JCL is created:

//INIT     JOB MSGLEVEL=1
//INIT     EXEC INIT
