just getting started in MASM (if you can't tell.. hehehe)

Code Select Expand

;use direct offse to move four values from Uarray to EAX
.386
.model flat,stdcall
.stack 100h
INCLUDE <c:\masm615\include\GraphWin.inc>

.data
Uarray WORD 1000h,2000h,3000h,4000h

.code
main PROC
mov EAX,Uarray ;put 1000h in register EAX
mov EBX,Uarray+4 ;go to offset of 2000h and put in register EBX
mov ECX,Uarray+8 ;go to offset of 3000h and put in register ECX
mov EDX,Uarray+12 ;go to offset of 4000h and put in register EDX

call DumpRegs ;show registers

main ENDP
end MAIN

and

Code Select Expand

;implement followint expression: EAX = -val2 + 7 – val3 + val1
.386
.model flat,stdcall
.stack 100h
INCLUDE <c:\masm615\include\GraphWin.inc>

.data
val1 SDWORD 8
val2 SDWORD -15
val3 SDWORD 20

.code
main PROC
mov EAX,val2 ;EAX = -Fh
neg EAX ;EAX = Fh
add EAX,7 ;EAX = 16h
sub EAX,val3 ;EAX = FFFFFFFFFFFFFFFF6h
add EAX,val1 ;EAX = FFFFFFFFFFFFFFFFEh

call DumpRegs

main ENDP

drapaki,
I see you are using the masm615 package. Updates for that package are now in a package called GeneSys. masm615 has been withdrawn but if you have any problems with it, Vortex and I will still support it.

Remove the line,

Code Select Expand


.stack 100h


32 bit PE files set the stack limit if needed with the linker.

Your application will not exit correctly, it needs a call to ExitProcess().

Ensure that the "DumpRegs" procedure is available or you will get a linker error.
