14. Parameter Declarations

• PROC directive may include parameter declarations: label PROC attributes USES reglist, parameter:tag, parameter:tag, ...

• Parameter declarations allow assembler to

  1. calculate necessary offsets for you

  2. let you refer to parameters by name.

  For example,

      add2nums PROC NEAR32 C, arg1:DWORD, arg2:DWORD
                  mov     eax, arg1
                  add     eax, arg2
                  ret
      add2nums ENDP
