min max

[Peter M]

It would seem that the MIN command does not work in the simulator

let w0=w0-1 min 0

when using this w0 just rolled right on by back to 65k

let w0=w0+1 max 1023

Yet this worked as expected?

So unless i've done something dumb (wouldn't be the first time, won't be the last)

You can't use this statement as you intend because of overflow - PICAXE doesn't support negative numbers.

if w0 = 1
so w0 = 1 - 1 which is 0, correct

if w0 =0
so w0 = 0 - 1 which is 65535, which is greater than 0, still correct.

yep.. Thanks (I did try it at 1 but forgot to set w1 at 1)

like I said won't be the last!
