“…One of the findings of the statistical studies on APL programs [5,6,73 was the great disparity in sizeapproximately 10 to I -between typical FORTRAN and APL programs. More specific comparisons between alternate language versions of the same algorithm also bear this out.…”

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.

An 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 illustrates that the setup time can often be eliminated or reduced greatly, producing code fragments that are more than 300 times as fast in favorable cases. Further work on the compiler should make some compiled code fragments about 500 times as fast as interpreted programs in favorable cases. In less favorable cases, performance improvements of a factor of two are commonplace. Many opportunities remain to improve the performance in such cases. A production compiler based on this work might allow use of APL to solve problems that in the past have been prohibitively expensive for APL solution.

“…Robinson and Torsun (41) did an additional study on the use of FORTRAN. Bingham (11,12) and Saal and Weiss (42) have examined characteristics of APL programs. PL/l has been the target of studies by Elshoff (16,17,18), while features of COBOL usage have been reported by Chevance and Heidet (14) and Salvadori, Gordon, and Capstick (43).…”

Content analysis of APL defined functions

Abstract: The content of defined functions in 51APL workspaces are analyzed.The static content, rather than dynamic usage, is given. The two source APL systems were Burroughs APL/700 and IBM APL/360 XM6.This data identifies those portions of the APL language that actually appear in workspaces.
