Assembly coding with masm32

In assembly coding, working with masm32.

How can i put a value into a variable, that is not defiened at the .data segment, but by the LOCAL decleration?
thous: 

.486                                    
.model flat, stdcall                    
option casemap :none

.data  

.code  

start:  

call main  
exit  

main proc  

LOCAL dewit:DWORD

mov dewit, 0
print dewit  

ret  

main endp  

end start

I tried something like this: 

Mov dewit, 0

It didnt work. However, this code: 

Mov dewit, input("enter a number")

Did put a value into it.

Anybody?

** the LOCAL decleration can only be in a procedure

Solution

  • Since you are using MASM32 If you are trying to print out a 32-bit value try doing it this way with str$:

    print str$(dewit)

    This converts the 32-bit value at the memory location dewit into a string, and that string is printed on the console. This also work for an immediate value as well:

    print str$(100)

    And a register:

    print str$(eax)

    You can use $ustr as well if you wish to print the unsigned value.

    These macros are described in the High Level Macro help that comes with MASM32 SDK
