11S043 APL-11 for RSTS/E Version: 1.0, June 1981 Submitted by: Digital Equipment Corporation Operating System: RSTS/E V7.0 Source Language: MACRO-11 Memory Required: 40K bytes Keywords: APL, Language Interpreters, Programming Languages Abstract: APL-11 is an interpreter for the APL language, a mathematically structured programming language, that features many functions which operate on arrays of arbitrary order. It is used as a general data-processing language as well as a mathematical tool. APL can define recursive procedures that use local variables. The special APL character set can be used on a terminal that supports it, or can be simulated with mnemonic escape sequences on non-APL terminals. The user can interact with the APL interpreter to examine and change variables, alter statements without recompilation and trace program action. Release Notes are distributed with each order. Documentation available in hardcopy only. Media (Service Charge Code): User's Manual (EC), 600' Magnetic Tape (MC) Format: DOS-11
