JMP function

[bawrobin]

Hello.
Please help.


Here is my code:

Code Select Expand


.686p

.model flat, stdcall

option casemap:none


includelib \masm32\lib\kernel32.lib
includelib \masm32\lib\user32.lib
include \masm32\include\kernel32.inc
include \masm32\include\user32.inc
include \masm32\include\windows.inc





.data

MsgText     db 'Calculating results - %d',0
MsgTitle    db 'Hello',0
buffer      db 100 dup(?)
number EQU 80




.code
start:

mov eax, number

jmp sign1

sign1:
sub eax, 15

sign2:
add eax, 20

   invoke  wsprintf,ADDR buffer,ADDR MsgText,eax
   invoke  MessageBox,0,ADDR buffer,ADDR MsgTitle,MB_OK
   invoke  ExitProcess,0

end start




Please help.
I need to ignore "sign2:*" code after executing jumping and reading to sign1. So, I need that results must be 65. Please help. How to ignore reading of sign2 after jumping to sign1.

  sub eax, 15
  jmp around2

around2:

Another here:

Code Select Expand

sign1:
  sub eax, 15
  sub eax, 20
sign2:
  add eax, 20

When it pass over the add eax, 20 it will be like nothing happen, but lol i just go to far with the assumption ^^.

Code Select Expand

sign1:
  sub eax, 15
  push offset lol
  ret
sign2:
  add eax, 20

Too far again...
