8769 BASIC Keyword Execution Address List
Submitted by Steve Fewell
Description:
The BASIC ROM contains a list of execution addresses between locations &8769 and &884C.
For each address, the list contains 2-bytes of information specifying which address should be
jumped to in order to execute that command (LSB first, MSB second).
The table contains an address for each Keyword Token in the range &8E to &FF.
Plus three extra addresses the meanings of which are currently unknown.
BASIC jumps to the appropriate Execution address, depending of the value of the Token.
Note:
The following Tokens do not need an execution address, as BASIC handles these tokens
separately (either in relation to other Keywords or as part of expressions):
&80 - AND
&81 - DIV
&82 - EOR
&83 - MOD
&84 - OR
&85 - ERROR
&86 - LINE
&87 - OFF
&88 - STEP
&89 - SPC
&8A - TAB(
&8B - ELSE
&8C - THEN
&8D - Missing [+ ASCII 32 (Space)]
