ABSTRACT:
A parser is dynamically reconfigured. Parse Control Records are read into memory. They are inserted into corresponding Parse Table Entries in a Parse Table in memory identified by a Parse Table Entry Identifier in each Parse Control Record. Each of the Parse Table Entries corresponds to a single command, and includes an ordered series of allowable parse states for that command. After a string of text has been tokenized into an ordered sequence of tokens, the ordered sequence of tokens is evaluated pursuant to the allowable parse states in the Parse Table Entries to determine whether the Text String has a valid syntax.
