System information

command: CP/M command line. In general, a CP/M command line has three parts: the
command keyword, command tail, and a carriage return. To execute a command, enter a CP/M
command line directly after the CP/M prompt at the console and press the carriage return or enter
key.
command file: Executable program file of filetype COM. A command file is a machine language
object module ready to be loaded and executed at the absolute address of 0100H. To execute a
command file, enter its primary filename as the command keyword in a CP/M command line.
command keyword: Name that identifies a CP/M command, usually the primary filename of a
file of type COM, or a built-in command. The command keyword precedes the command tail and
the carriage return in the command line.
command syntax: Statement that defines the correct way to enter a command. The correct
structure generally includes the command keyword, the command tail, and a carriage return. A
syntax line usually contains symbols that you should replace with actual values when you enter
the command.
command tail: Part of a command that follows the command keyword in the command line. The
command tail can include a drive specification, a filename and filetype, and options or
parameters. Some commands do not require a command tail.
CON: Mnemonic that represents the CP/M console device. For example, the CP/M command
PIP CON:=TEST.SUB displays the file TEST.SUB on the console device. The explanation of the
STAT command tells how to assign the logical device CON: to various physical devices. See
console.
concatenate: Name of the PIP operation that copies two or more separate files into one new file
in the specified sequence.
concurrency: Execution of two processes or operations simultaneously.
CONIN: BIOS entry point to a routine that reads a character from the console device.
CONOUT: BIOS entry point to a routine that sends a character to the console device.
console: Primary input/output device. The console consists of a listing device, such as a screen or
teletype, and a keyboard through which the user communicates with the operating system or
applications program.
Console Command Processor: See CCP.
CONST: BIOS entry point to a routine that returns the status of the console device.
