Why isn't "a|b|c" equivalent to "a or b or c"? It is so much more compact.. I want to use it instead..


I tried putting "| equ or" at the top of the file but it doesn't work.. please help Confused

"|" is a logical operator.

"or" is a binary operator.

It is explained in the fasm manual.

Doesn't a binary or work wherever a logical or does?

true logical or false = true
true(1) binary or false(0) = true(1)

How do I make the | work like binary or? It would save much space.. each time, " or " takes 4 characters, "|" would only take 1.. this makes a big difference in readability with long masks.. please help..

If what you're ORing doesn't have overlapping bits, you could use +.
