An APL emulator on System/370
ANTHONY HASSITT, L. E. Lyon · IBM Systems Journal · 1976
Emulation of an APL machine on a System/370 is exemplified by the APL Assist, a microprogram that enables APL expressions and defined functions to be executed at the hardware level. This paper discusses what the APL Assist does, how it works, and the way it interacts with System/370 software. Execution times for APL programs with and without the Assist are compared.
