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)
