* POINTERS TO STRINGS OF BASIC COMMANDS *
*****************************************
*
* This table, with base at CC08, is used for
* printing the Basic instructions during a
* listing.
*
* From the TOKEN, the address in this table can
* be found by:
*      CC08 + 3x TOKEN = address in table
* This is done by a routine on 0ECCC.
*
* The address given points to the memory location
* on which the particular string can be found.
*
* The data byte after the address is an offset
* with base at 0ECF8. Therewith the instructions
* can be found about what to print after the
* Basic statement (when performing LIST).
