Running a "legacy" MVS infrastructure "around" the JVM

Post by Scott Fagen » Mon Feb 22, 2021 10:52 am

Hello, I wasn't able to find something like this on the forum, if it's been discussed, please redirect me...

I'm trying to set up some MVS infrastructure in an address space that lives and interacts politely with programs in the JVM.

I found this in JZOS -- https://www.ibm.com/developerworks/syst ... l#listing2 -- which shows how to launch Java from JCL. Is it a bad idea to modify this example to use similar JCL, but instead of EXEC PGM=JZOSVM14, running my "legacy" initialization program (EXEC PGM=MYINIT). Upon completion, MYINIT would then LINK to JZOSVM14.

If this would theoretically work, is there anything I should avoid, watch out for, or make sure that I do?

Thanks,
Scott
