mov eax,[eax] problem

[thomasantony]

Hi,
  I get this error with mov eax,[eax]

error A2070: invalid instruction operands

This happens when I use it in winasm. I made a small test.asm file and compiled it from the console and it worked Ok. Can someone tell me whtas wrong? The whole log of winasm IDE is this



C:\masm32\Bin\ML /c /coff /Cp /nologo /I"C:\masm32\Include" "C:\Projects\Masm32\Mx Lookup\mx.asm"

Assembling: C:\Projects\Masm32\Mx Lookup\mx.asm

LINK : fatal error LNK1181: cannot open input file "C:\Projects\Masm32\Mx Lookup\mx.obj"

Make finished. 2 error(s) occured

But when I compile this specific file in console also I get this error. Whats wrong? I stop getting the error if I do
mov eax,dword ptr[eax]

Hi,
  I found out the problem right away. Stupid of me :red . I had used assume on eax making it as a pointer to a structure. It started working okay when I did :

assume eax:nothing

You will get the same error with:

assume eax:ptr byte

And  "error A2022: instruction operands must be the same size" with:

assume eax:ptr word
