Can you elaborate a little on this...I tried the following routine and
got nowhere, just a continuous stream of 21845 output:
100 REMark try to read pointer co-ordinates
110 driver_address = CHAN_L(#0,4)
120 REPeat loop
130 PRINT
PEEK_W(driver_address+HEX('20')),PEEK_W(driver_address+HEX('22'))
140 END REPeat loop
Adding $18 as you suggested made no difference at all.
(CHAN_L is Simon Goodwin's routines for extracting info from channel
definition block).
