XPL0 (original) (raw)

XPL0 is a computer programming language that is essentially a cross between Pascal and C. It looks somewhat like Pascal but works more like C. It was created in 1976 by Peter J. R. Boyle who wanted a high-level language for his microcomputer and wanted something more sophisticated than BASIC, which was the dominant language for personal computers at the time. XPL0 soon proved its worth in a variety of products based on the 6502. These embedded systems would otherwise have had their code written in assembly language, which is much more tedious to do.
