 * This program converts your SEQ files as well as expands tokenized
 * C64/128 BASIC programs into 7-bit ASCII text. Unprintable characters
 * can be shown as hexadecimal codes in parenthesis, via `-c' option.
 * It is also possible to convert programs from ascii listings into
 * tokenized basic v2.0, v3.5, v4.0, v7.0 or simon's basic programs. This
 * program also replaces certain control code names with the actual codes.
 *
 * A list of Toolkit Basic (published by Compute! Books) token codes
 * would be greatly appreciated. (-:
 *
 * Runs on UNIX or Atari ST.

29/01/2009 gpz:
- raised length of input buffer from 256 to 256*8

   the line may contain 256 _basic tokens_, some of which may either be
   represented as literal basic commands or as petsciicodes in braces -
   either of these representations is a few characters long so the input
   buffer must consider this

   note: this is still ugly =P
- added recognition of control codes in the form {123} (decimal number)
