How to Jump to a memory address using ASM

[A.I]

Anybody who have knowledge on ASM?

I'm looking for a method to continue program execution from a label. Basically, I'm trying to do 'Goto' in ASM. I know this is done via !JMP, but it's not that simple. I'd like to Jump to a memory address defined by a variable. Like this:

Code: Select all

address = ?label ; PureBasic variable

!JMP [_address]

    ;This line will never be executed
label:
    ;The execution continues here

I know there's an alternative method by using the 'GotoEIP()' command from the OnError-library. However, I wonder which is faster since 'GotoEIP' has some CALLs in the ASM output.

Code: Select all

address = ?label ; PureBasic variable

!JMP [v_address]

MessageRequester("Test", "1")
    ;This line will never be executed
label:
    ;The execution continues here
MessageRequester("Test", "2")

You have forgotten the v at v_adress.

Notice you dont have to use the [v_value] unless you use the ! before.

What?! The answer was that simple. *put his hand on his forehead*

Thankyou very much.
