INTERACTIVE SNOBOL4 SYSTEM FOR THE SDS 940,

Abstract

The SDS 940 SNOBOL4 system will accept programs written in a language which is basically compatible with a subset of Bell Labs' November 22, 1967 version of SNOBOL4. The SNOBOL4 system permits programs to be created, run and debugged interactively. The principal data object in the SNOBOL language is a string of characters. The language permits building up longer strings from shorter strings through concatenations. In addition, through pattern matching, strings can have their contents tested and have the matched substrings assigned to string variables. Other features of the language are arithmetic on integer strings, built-in functions for general use, and programmer defined functions which may have local variables and can be recursive to arbitrary depth. Input-output from files is provided as well as from the teletype. (Author)
