Google was not very forthcoming about a definition of "native CICS". However, it is not aseparate product, if that is what you are thinking. What is, probably, meant by that term is using CICS at the CICS command prompt where you enter CICS commands and start transactions etc.
CICS commands you can look up yourself in the CICS command manual.
