PL/M

The PL/M programming language (an acronym of Programming Language for Microcomputers) is a medium-level language developed by MAA (later Digital Research) in 1972 on behalf of Intel for its microprocessors. PL/M is no longer supported by Intel, but aftermarket tools like PL/M-to-C translators exist.

The language incorporated ideas from PL/I, ALGOL and XPL, and had an integrated macro processor. Programmers who are familiar with the Pascal language find it easy to transition to PL/M. PL/M was the original implementation language for the CP/M operating system. There were PL/M compilers made for the following processors/controllers: Intel 4004, 8008, 8080, 8051, 8086, 286, and 386.

During the late 1970's and 1980's, Intel produced a series of workstations called Isis, designed for use in developing firmware for systems using the Intel microprocessors. A variety of emulation solutions and supporting hardware were available from Intel as well as from third parties. These emulators usually consisted of specialized hardware that was connected between the workstation and the target hardware's microprocessor socket. The programmer could then take control of the target system to a very fine level to inspect and modify virtually every aspect of the microprocessors' operation.

Language: A language is a system of expression and communication. Individual languages use sound, gesture, and other means to express and communicate concepts, emotions, ideas, and thoughts. Expressions of a language are analysable into words, whose meanings are usually conventional. The word "language" is ...
