Why can't I do this:

proc test
local blah[20]:BYTE
mov esi,blah
endp

I know "blah" is 20 bytes on the stack, but why cant I reference it as though it was on the heap?

blah is not fixed offst but related to the current ebp, thus, should be:
lea esi,[blah]

Thanks shoorick. That makes sense and works fine. Smile

I also just found out that using "addr blah" with extended headers appears to achieve the same outcome.
