What is the best way of defining local valiables outside of a proc, for example at an entry point? Anything better than reserving stack space and declaring virtual variables? Anything better than:

Code:
.code
 start:
        call    main
        ret

There are no local variables in your example. What is it you want to do? Local variables are always on the stack when the program runs but you seem to be asking how to have them, somehow, not on the stack?

For the code I think that he is probably wanting this?
Code:
.code
proc start ; Instead of "start:"
;locals here

;code here

invoke ExitProcess, 0 ; Or just "ret" BUT Windows documentation is not clear about this and could not work on future Windows versions.
endp
