Could someone explain this to me, preferably with a floats example to! =, equal <>, not equal (less than or greater than, pascal syntax i think) <=, less than or equal >=, greater than or equal _________________ redghost.ca |

Lol, sorry I wasn't clear! I meant the FASM equivilant of those operators. For exampe + is:
Add a,b What's the instruction for those operators? |

Sorry to be a pain, but can you give me a specific example on how to use this - I get an error when I try to use any of those commands, the operators are invalid apperantly. Aren't they jump instructuons?

I think you will find this tutorial helpful. It uses nasm but nasm's syntax is similar to fasm's.

Code: cmp dword [v_variable], eax ; compare v_variable with the value in eax. And, then, jump to the adequate label: Code: je .equal_to ; Jump if v_variable is equal to eax, etc. jne .unequal_to jg .greater_than ; for signed numbers jl .less_than ; for signed numbers ja .above ; for unsigned numbers jb .below ; for unsigned numbers jge .greater_than_or_equal_to ; for signed numbers jle .less_than_or_equal_to ; for signed numbers jae .above_or_equal ; for unsigned numbers jbe .below_or_equal ; for unsigned numbers |
