Resum:The objective of IBM Corp.'s APL IL Interpreter Generator is to solve the problem of creating APL interpreters for different machines at a minimum cost. The objective has been accomplished by writing an APL interpreter in a specially designed programming language, the Madrid Scientific Center Intermediate Language (IL), which has very low semantics but high-level syntax. The interpreter is translated to each target machine language by easily built compilers that produce high-performance code. The IL compilers are usually written in APL or APL2, which makes them very easy to adapt to new target machines. The APL IL Interpreter Generator has been used to generate 8 APL and APL2 systems as well as an IBM Japan educational product called LETSMATH, which includes the interpreter without the user being aware of it.
