64 bits

Code:

macro CreateCalladress address,Name {
        local ..return
        push  ..return
        jmp   qword address
..return:        
        Name equ ..return-4
}   
CreateCalladress ProcA,MyProcA
invoke MyProcA

But IDA pro show jmp short !
This breaks my idea.

When you say far jmp, do you mean long jmp?

Code:

use64
addr dq 0x1234567890abcdef
jmp [addr]

jmp [rip+0]
dq my_address

this form of jump takes 14 bytes.
