INCLUDE is used ONLY on MVS/ESA Version 4 or higher systems to name an INCLUDE group. An INCLUDE group is a set of one or more valid JCL statements that are stored together in a JCLLIB data set or a system procedure library, and that are read in and used to replace the INCLUDE statement itself within the job. Any number of INCLUDE statements can be used in a job, but the name field value used on each should be unique within the job. The INCLUDE statements can appear in a job anywhere after the JOB statement, but may not appear between a CNTL and ENDCNTL JCL statement.
