SET is the ANSI standard for variable assignment, SELECT is not. SET can only assign one variable at a time, SELECT can make multiple assignments at once. If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one) When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value) As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.


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.
