Can anyone tell me why I get the output listed below from this code? I was expecting the = -1 to be true and 0 - 1 to be -1 .

code:
parenlevel var word
pause 2000
parenlevel = 0
serout s_out,i9600,[sdec parenlevel]
parenlevel = parenlevel - 1
if parenlevel = -1 then
serout s_out,i9600,["negative"]
endif
serout s_out,i9600,[13, sdec parenlevel]
end

Output:
0
65535

Setup:
Studio 1.0.0.14
Basic Atom 28 Rev d

Yep,

You have: parenlevel var word

SO parenlevel is an unsigned word. If you wish for it to show up as -1, you might try:
parenlevel var sword

Thanks, that was it. I read studio doc and discovered sbyte and slong too.
