max and min values

[Puuhaaja]

irin [400,main], C.2, b0
if b0 = 18 then inc b5 
elseif b0 = 19 then dec b5
end if

I want that b5 will never grow bigger than 9 and smaller than 0

I tried different kind of

let b5 = max 9

codes but didn't get it workin
I'd like to use max/min commands because

if b5 = 10 then let b5 = 9

etc codes need much more space because there's so many places where I need that.

Try this:

irin [400,main], C.2, b0
if b0 = 18 and b5 < 9 then inc b5 
elseif b0 = 19 and b5 > 0 then dec b5
end if

I'd like to use max/min commands

Using MIN and MAX commands saves a few (4) bytes:

irin [400,main], C.2, b0
if b0 = 18 then 
  b5 = b5 + 1 MAX 9 
elseif b0 = 19 then 
  b5 = b5 MIN 1 - 1
end if

Note that if you try b5 = b5 - 1 MIN 0 and b5 is already 0 then b5 = b5 - 1 ==> 255 so the MIN 0 will not create the 0 lower limit
