An APL interpreter written in APL
Proceedings of seventh international conference on APL - APL '75, 1975An 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. Extensions already implemented on it include complex number arithmetic, and reduction and scan operators ...

This paper is a discussion of the evolution of the APL language, and it treats implementations and applications only to the extent that they appear to have exercised a major influence on that evolution. Other sources of historical information are cited in References 1-3; in particular, The Design of APL [1] provides

In this paper we discuss a modification to APL/360 which allows rather interesting modes of use of APL, such as subtasking, multitasking, working without a terminal, communicating between terminals synchronously or asynchronously, etc.By subtasking we mean the subdivision of a main program into parts called subtasks, which may be executed concurrently,

A course in programming languages should teach students about the syntax and semantics of programming languages, as well as make them aware that a good choice of a programming language can often make a problem much easier to solve. This last point can best be made by giving students a problem that is much easier to solve in one language than in most ...

@FX functions. The canonical representation of a function can be revised using a few simple commands that can find, delete, replace, or add characters and character strings in the function, list the revised function or portions of it and finally fix the revised function provided it is formally acceptable for fixing.Following is a complete description ...

APL is a formal, imperative language. Because it is imperative, a sentence may be called an instruction, and may be executed to produce a result. In illustrations used here, an instruction will be indented, and the result of its execution will be shown on the following line without indentation.

This document describes a graphic facility within APL. The terminals are assumed to be inexpensive timeshared graphic terminals equipped with an APL character set. We first describe functions in a graphic workspace and then APL primitives for graphing.Graphic APL is a shared processor at Irvine, called APLG. The current version is 6.1.

APL\360 is an experimental, conversational System/360 implementation of APL, the Iverson language. It provides fast response and efficient execution to a large number of typewriter terminals. With 40 to 50 terminals connected and in normal use, each with a block of storage (called a workspace) allocated, reaction time (defined as the time from ...
