 CPS support for the IBM 2741 "break feature" most likely influenced the eventual user group support for the "break feature" and the IBM 1050 terminal on IBM Administrative Terminal System (ATS/360), as many IBM customers which operated CPS also operated ATS/360.CPS was ultimately superseded by TSO.An IBM program product was offered which provided limited CPS functionality under TSO, intended mainly as a "bridge" between CPS and TSO.
