| (...) Disclaimer: I didn't try ANYTHING of this... According to Kekoa's Internals, the ROM routine 0x3250 (0x3266) with parameter 0x1770 sets the IR range to long (short). So you need to do something like: push 0x1770 jsr 0x3250 pop ; Stack should (...) (24 years ago, 27-Dec-00, to lugnet.robotics.rcx.pbforth)
