6.14.9.13.2. Code Formating

@F{start_code_line} is called to begin a line of code. Any count is placed at the beginning of the line.

Ending a line of code is accomlished by @F end_code_line. It simply adds a new line to the output stream.

@F write_code_fragment is called repeatedly for each token in the code stream. The parameter @F markup is the token type. Currently only comments and keywords are displayed differently. This code assumes that the font used to display program text has an @I Oblique form. This is true of Courier.
