Abstract
The design of a high performance APL system is presented along with an evaluation of the performance improvement measured on a partial implementation. The system contains a compiler which translates APL into the instructions of a virtual APL machine. Numerous special techniques suitable for optimized interpretation of this virtual machine entirely in software on a System 370 are described. The overhead for executing APL programs has been reduced by a factor ranging between 5 and 10 when compared to conventional interpretive systems.

A software high performance APL interpreter
APL '79: Proceedings of the international conference on APL: part 1The design of a high performance APL system is presented along with an evaluation of the performance improvement measured on a partial implementation. The system contains a compiler which translates APL into the instructions of a virtual APL machine. ...
An APL interpreter written in APL
APL '75: Proceedings of seventh international conference on APLAn APL interpreter has been written in APL. It includes a set of interacting APL functions that accept quote-quad input and act on it in the same way as APL itself would. The interpreter will be used to test some proposed APL language extensions. ...
A performance comparison between an APL interpreter and compiler
APL '83: Proceedings of the international conference on APLAn analysis of the execution of several simple APL statements illustrates that interpretive overhead in the form of setup time is awesome, and is on the order of 100 times as much as the per-element time. Comparison with an experimental compiler for APL ...
