''Notes:''
* The &ff code is used as a prefix for more keywords. See the table below for the list of keywords using this prefix.
* &e2,&e8 and &e9 are not used
* &7c ("|") is a character prefix used to identify a RSX command.
e.g. "|DIR".
An RSX is encoded in a BASIC program using the following structure:
Offset Count Description
0 1 "|" character prefix
1 1 8-bit byte offset to tokens following RSX name.
2 x RSX name. (Last character of name has bit 7 set to "1", all other characters have bit 7 set to "0")
* This token identifies a integer (16-bit) number. The two bytes following this token is the number, stored low byte then high byte. e.g. &19,&2d,&00 represents the integer number "&002d"="45".
* This token (&0B) is changed at run-time to &0D
