(...) You don't really need asm to do this. Due to a side-effect of how the bytecodes are implemented, you can set the slope value simply by adding it to the 'mode' parameter... // use a slope of 10 for light sensor on port 1 SetSensorType(SENSOR_1, (...)

For me, it makes malloc() and dll work perfectly. BTW, there are some minor flaws in dll[x], (...) (25 years ago, 2-Mar-00, to lugnet.robotics.rcx.legos)

It looks like it's not a bug in legOS, but in the RCX hardware: Memory from 0xfb80 to 0xfd7f is simply NOT WRITEABLE, or more exactly, always read as 0xff, at least on my RCX !

All, I have tried various ways to put asembly in my NQC programs. I have copied stuff from the header files but it does not work. I would like to use the slope parameter of the SetSensorMode opcode, but NCQ does not support this. That is why I need (...) (25 years ago, 1-Mar-00, to lugnet.robotics.rcx.nqc)

Thanks for your help. I was also wondering if there is a way to have the motor turn off at any time in the program when the touch sensor is pushed, rather than having to re type the until statements a bunch of times. would I have to use a task for (...)
