Dear all, I have managed to pin down the problem a bit further. Please look at the following program: program foo { const c10 = 10 main { forever {} } task test { local v2f local v2e local v2d v2f = 1 v2e = 2 v2d = v2e * c10 } } If you download this (...)

Tom's understanding is correct. All RCX programs are allocated from the same memory space. The RCX firmware provides "garbage collection" on this memory space so that whenever a program or subroutine is deleted, all programs/subroutines in higher (...) (24 years ago, 1-Mar-01, to lugnet.robotics)
