A Machine-Independent APL Interpreter
Manuel Alfonseca, M. L. Tavera · IBM Journal of Research and Development · 1978
The problem of writing machine-independent APL interpreters is solved by means of a systems programming approach making use of an intermediate level language specially designed for that purpose. This paper describes the language, as well as the procedure used to build universal interpreters. Three compliers that translate this language for three different machines have been written so far, and an APL interpreter has been finished.
