How would you...

In C++ I have a line thats:

Code Select Expand

Temp [ 1 ] = Temp [ 2 ];

How would I do this in MASM? When I run it through MSVC it puts it out as:

Code Select Expand

mov al, BYTE PTR Temp [ebp+2]
mov BYTE PTR Temp[ebp+1], al

But would I really use EBP for this?

You would most likely just use the label, the assembler will generate the offset from EBP for locals and parameters. All local and parameter data resolves to an offset from either EBP (normally used for parameters) or ESP (normally used for locals). Of course since C++ sometimes uses EBP as a GPR all bets are off but I would suspect that temp is a parameter pushed onto the stack before the call. Since there is no 1/4 stack operation in 32 bit programming (ie you cannot push a single byte - all stack operations have to be DWORDs) the data is extracted as an offset from the temp label and resolved into byte sized chunks.
