问题
I have tried compiling the following code in FASM:
mov DWORD PTR [ebp - 4], 1234567
It gave me an "Invalid Expression" error. However the following code worked:
mov DWORD [ebp - 4], 1234567
So does FASM uses Intel Syntax (I am assuming that the first line of code is compliant with Intel Syntax)?
回答1:

Unlike MASM (and others), FASM doesn't need "ptr".

Yes.
But there are some differences between different assemblers, for example:
Loading an address:
- MASM:
mov eax, offset memvar - FASM:
mov eax, memvar
Loading a value:
- MASM:
mov eax, memvar - FASM:
mov eax, [memvar]
I suggest you to read the FASM Programmer's Manual.
