 | | equiv. to SetRandomSeed() for firm0309?
|
|
Is there a way to do the equivalent to SetRandomSeed() with 1.x firmware (3.09) which--if I understand correctly--is only available for RCX2 (3.28)? Maybe some kind of low level code to set the appropriate memory address? Thanks, Rik. (24 years ago, 22-Feb-01, to lugnet.robotics.rcx.nqc)

It is my understanding that the RCX has 32 "spaces" for variables, I am trying to set variable A or 10 to the value of 100 and then evaluate it in an IF statement.

Tobias, 'multi-tasking' means that several tasks run simultaneously. For example, a robot arm could grab, lift and swivel, one after the other, as functions, or simultaneously, as tasks. Or, the RCX could play a tune and a walker could walk, one (...) (24 years ago, 5-Feb-01, to lugnet.robotics.rcx.nqc)
