The SIMPL Family of Programming Languages and Compilers

The SIMPL family is a set of structured programming languages and compilers under development at the University of Maryland. The term 'family' implies that the languages contain some basic common features, such as a common subset of data types and control structures. Each of the languages in the SIMPL family is built as an extension to a base language. The compiler for the base language is written in the base language itself, and the compiler for each new language is an extension to the base compiler. (Author).
