Description

Use to read a string token from a file. A string token is simply a series of characters, separated by any number of delimiters. For example, the sentence "ShogunPost is for editing" is composed of the tokens "ShogunPost", "is", "for", and "editing", assuming the delimiter is a space. You can " tokenize" the contents of a file for easy parsing.

Note that this command can only be used with text files (files opened without the -b flag). Command will fail if at the end of the file.
