The XPL language is a dialect of PL/I created by McKeeman, Horning and Wortman and documented in their book "A Compiler Generator" published in 1970. XPL is a procedural language with structured program flow. The language supports integer arithmetic and logical operations. XPL supports dynamic string variables and powerful character string manipulation features. The compiler and the runtime are written in C. The compiler generates C source so anyone with a working C compiler can compile and execute code written in XPL. XPL and the BNF analyzer were the cutting edge of compiler technology 50 years ago. This release includes both the compiler and the BNF analyzer written in the late 60s. You can download the source here: https://sourceforge.net/projects/xpl-compiler
