TOKENDEF

take a string and check if it any one in list of tokens. The entry TOKENDEF defines pair of token string and its integer value that identifies the token. Parsing of string is done by comparing the input token in sequence against each entry in the table. Not very fast, but very convenient. More...

Detailed Description

take a string and check if it any one in list of tokens. The entry TOKENDEF defines pair of token string and its integer value that identifies the token. Parsing of string is done by comparing the input token in sequence against each entry in the table. Not very fast, but very convenient.
