nasm labels

[scgtrp]

What is the difference between these?

Code: Select all

foo db 0

Code: Select all

foo: db 0

The only difference I can find is that NASM warns me if I have a label on a line by itself without a colon.

I think the issue is that NASM will accept labels without colons, but wants you to use colons. It's probably just in case they want to add a feature that makes it necessary for labels to have colons and break the improperly written code.

I rather tend to think that its warning that you may have mistyped an opcode (or macro name).
