INCLEVEL – Message level for INCLUDE statements

By default, any statements run as a result of INCLUDE statements is listed only when either the MSGLEVEL is 3 or higher, or the statement fails. Use INCLEVEL to specify an alternative message level for listing the contents of the included members.

OPTIONS INCLEVEL(1)
All included statement are listed at the same level as normal SYSIN commands.
OPTION INCLEVEL(2)
All included statements are listed at the same level as any statements generated by automatic SELECT, DELETE, or EXPAND options.
OPTIONS INCLEVEL(3)
All included statements are listed at the same level as statements within the member referenced by the FILESPEC symbolic in the JCL.

Levels 4 and 5 are not available for INCLUDE statements, because these levels are reserved for internal Workload Automation Programming Language commands.
