ABSTRACT

Parser

PARSER is a generic parser that functions in a manner similar to the ARGC/ARGV parser of UNIX. It contains one procedure, PARSE, which accepts a string as input and returns ARGC, a count of the number of tokens in the string, and ARGV, a vector of strings, each string containing a token.

PARSER is instantiated with two strings (DEL for DELIMITER and DEL_TOKEN for DELIMITER_TOKEN). The DEL string is composed of characters which delimit each token (and are not a part of the token). All characters less than space are automatically delimiters, and the DEL string should contain at least one character (such as a space). DEL_TOKEN is a string composed of characters which delimit tokens and which are tokens themselves. If "=" is a DEL_TOKEN, for example, then "CAT= DOG" is composed of three tokens, "CAT", "=", and "DOG", where if "=" is a DEL, then "CAT= DOG" is composed of two tokens, "CAT" and "DOG". This assumes that the space character is a DEL.
