$JDMONITOR and HASJRCHK module

Hi all,

I have a question about a module that is displayed when you issue the $JDMONITOR command. The module in question is HASJRCHK. I am trying to find out exactly what this module does?

I have looked through JES manuals to find any reference to this as far as I can tell it seems to have something to do with the checkpoint level/modes? Not 100% sure about it though. Does anyone out there have any insight on what the purpose of this module is?

What I'd try is to see if there is a HASJRCHK member in SYS1.SHASSRC and see what the module header says. Hopefully it's not OCO. I do not have access to any recent z/OS release so I can't do it for you.
