11S025 APL-11 for RSX-11M and RSX-11M-PLUS Version: V. 2.0/2.1 June 1981 Submitted by: Digital Equipment Corporation Operating System: IAS, RSX-11M V3.2, RSX-11M+ V1.0 Source Language: MACRO-11 Memory Required: 40K bytes Keywords: APL, Language Interpreters, Programming Languages, Structured Languages/Programming 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 distributed with each order. Notes: APL-11 for RSX-11 V2.1 has been run in compatibility mode on the VAX, but is known to have a problem with terminal I/O coming out double-spaced. This RSX-11 version of APL-11 has updated sources on it (V2.1). Documentation available in hardcopy only. Media (Service Charge Code): User's Manual (EC), 2400' Magnetic Tape (PC) Format: DOS-11
