@MichaelBurr: I'm rather sure he just wanted the extra pair of rates; the /s was redundant In such cases, as the circumstances less than which /s tends to make a variation weren't achieved.
An assembly language is distinct to a particular Pc architecture, in contrast to most large-degree programming languages, which may be extra moveable.
So it isn't getting rid of offers around arguments; It is possibly getting rid of estimates across the route on the EXE you are functioning, or across the whole command line (or possibly round the initially fifty percent from the command line, which would be weird).
