PCL. 1. Printer Control Language. A {Document description language} used by {Hewlett-Packard} {Laserjet} printers, a superset of {HP-GL/2}. [PCL 5 Printer Language Printer Technical Reference Manual, HP 33459-90903. Versions: PCL 3, PCL 5]. 2. {Portable CommonLoops}. 3. Peripheral Conversion Language. A {Honeywell} command language for {file transfer} between I/O devices on the {CP-V} and {CP-6} {operating system}s. 4. ["PCL - A Process Oriented Job Control Language", V. Lesser et al, Proc 1st Intl Conf Distrib Comp Sys, IEEE 1979, pp.315-329]. PCLIPS. Parallel CLIPS - U Lowell. Concurrent independent CLIPS expert systems. They use 'rassert' (remote assert) to enter facts into each other's database. "PCLIPS: A Distributed Expert System Environment", R. Miller, CLIPS Users Group Conf, Aug 1990. E-mail: (?).

(Or People Can't Memorise Computer Industry Acronyms). PCMIA. {Personal Computer Manufacturer Interface Adaptor} PCN. 1. {Program Composition Notation}. 2. {Personal Communication Network}. PC-NFS. {Personal Computer Network File System} P-code. The {intermediate language} produced by the {Pascal-P} {compiler}. P-code is the {assembly language} for a hypothetical {stack machine}, the P-machine, said to imitate the {instruction set} of the {Burroughs 6700}. The term was first used in the Wirth reference below. {Byte} articles on writing a Pascal Compiler in {Northstar BASIC} (ca Aug 1978) also used the term. P-code was initially the intermediate code generated by the P2 compiler from ETH Zurich. P-code was later used as the intermediate language in the {UCSD Pascal System}, and in its two main derivatives, {Apple Pascal} and the {UCSD P-system}. Variants: P2 P-code, P4 P-code, UCSD P-code, LASL P-code. [Algorithms + Data Structures = Programs, N. Wirth, P-H 1976]. ["A Comparison of PASCAL Intermediate Languages", P.A. Nelson, SIGPLAN Notices 14(8):208-213, Aug 1979]. (2004-11-08) PC Pursuit. A {TELENET} service which enabled people to dial up {BBS}es in other cities for less than normal long-distance rates. PC Pursuit died because TELENET were too mean to upgrade beyond 2400 bits per second. (1994-10-17) PC-RT. An incorrect name for the {RT-PC}. (1995-04-06)
