The Howdy Glossary

PL/P is a general-purpose programming language specifically crafted for Prime Computer minicomputers, designed to operate seamlessly with the PRIMOS operating system. It integrates features of assembly language with those of higher-level languages, enabling programmers to develop efficient yet readable and maintainable programs. Inspired by COBOL and Fortran, its syntax supports structured programming constructs such as conditionals and loops, striking a balance between low-level control and high-level abstraction.

Prime Computer developed PL/P to optimize programming for their systems, combining the strengths of assembly language and higher-level languages into a single platform. This unique integration allows developers to write powerful code that remains comprehensible and easy to maintain, addressing the specific needs of Prime Computer's hardware environment. The dual nature of PL/P offers a distinct advantage in creating efficient programs without sacrificing clarity or ease of maintenance.

PL/P distinguishes itself from other contemporary languages like Pascal, BASIC, and C by merging assembly language efficiency with high-level readability. While Pascal was recognized for structured programming capabilities, BASIC for its simplicity, and C for portability and efficiency across various systems, PL/P provided an optimal blend tailored specifically for Prime Computer environments. This combination appeals particularly to programmers within the Prime ecosystem who require both performance optimization inherent in assembly language and the organizational benefits offered by structured programming elements from COBOL and Fortran.
