(...) No, it will not. Functions don't work like that, in general. If you want to call a function and have it run independently of the calling function, you must use execi() to start it. (24 years ago, 12-Mar-01, to lugnet.robotics.rcx.legos)

(...) The limit is in the checksum routine built into the RCX - it only does a sum up to 0xCC00! So you may need to fiddle with firmdl to allow a larger SREC image, but only checksum up to 0xcc00. Hope this helps. Ralph Hempel (24 years ago, 9-Mar-01, to lugnet.robotics.rcx.legos)

Hi!
