Equivalent Enterprise Server's CICS version to Mainframe's?

I havening looking for information on what is the equivalent version of Enterprise Server 7.0's CICS to Mainframe's and / or supported commands but without luck.

Does that information exists somewhere?

Is safe to assume that is that is syntax and functional compatible with ZOS's 4.2?

Would be nice to have a table with each API with what is and what is not supported and/or functional differences.
