control program
(foldoc) | Control Program
(CP) The component of IBM's {Virtual
Machine} (VM) that provides "guest support" for {operating
systems} that run on IBM mainframe compatible processors.
Cp does this by providing a seamless emulation of privileged
functions in the problem program environment.

ACF/NCP
(ACF/NCP, usually called just "NCP") The primary
SNA network control program, one of the ACF products.
ACF/NCP resides in the communications controller and
interfaces with ACF/VTAM in the host processor to control
network communications.
NCP can also communicate with multiple hosts using {local
channel} or remote links (PU type 5 or PU type 4) thus
enabling cross domain application communication. In a
multiple mainframe SNA environment, any terminal or
application can access any other application on any host using
cross domain logon.
See also Emulator program.

CPM
CP/M
(CP/M) An early microcomputer {operating
system} written by Gary Kildall of Digital Research for
8080 and Zilog Z80-based 8-bit computers.
Many of CP/M's features and conventions strongly resemble
those of early DEC operating systems such as TOPS-10,
OS/8, RSTS and RSX-11.
CP/M was very popular in the late 1970s and Bill Gates
suggested using it as the OS for the IBM PC. IBM wanted
to own and control the OS completely but could not get Digital
Research to sign a non-disclosure agreement, which killed the
deal. CP/M was virtually wiped out by MS-DOS after the
release of the IBM PC in 1981.
The file system of MS-DOS was patterned closely on CP/M's,
including the use of 8 + 3 (upper case) character file names.
The first version (MS-DOS 1.0) was even limited to a single
directory, like CP/M.
