(...) Lego's usage of the terms'local' and 'global' is a little different than what most people expect. In the RCX, global storage is available across all tasks while local storage is avaialble per task. This is different from the more traditional (...)

Hi, You can check the link of how to hook up servo (look for by Gary Livick's contribution): (URL) will be easy if you have HB Expansion board since you just connect the servo directly into it.

I'm working on some research with the Handyboard, and I don't know too much about programming it yet. I've figured out how to work the DC motors but not the servo motors, I think I've attached the pins correctly to the wires on the servo motor but I (...)

Hi John, (...) Yes ! Using more tasks you will get more local space (for each task 16). So maximum number of variables is 32+(16*10) = 192 (...)

When using the RCX2 target, the NQC manual (Section 2.2.4) states that 32 global variables, and 16 local variables (per task) are allowed. Does this mean that the whole program can only have 48 variables total when using only one task, ie. "main" , (...) (23 years ago, 20-Feb-02, to lugnet.robotics.rcx.nqc)
