To get the OPERPARM data to be passed, operator command validation must be active. By default ACF2 ignores those calls. If you only want this for the EMCS under z/OSMF and not all operator commands to be validated, then a SAFDEF record is needed with a PROGRAM of CONSOLE.
INSERT SAFDEF.OPERCMD ID(OPERCMDS) MODE(GLOBAL) RACROUTE(REQUEST=AUTH,CLASS=OPERCMDS) PROGRAM(CONSOLE)
This allows the EMCS to pick up the OPERPARM settings.
Note: for the extract of the OPERPARM profile to work, you must create a logonid that matches the name of the console. e.g. ABCDEFGH
