What does PURE mean in startup assigns?

What does that switch do?

You probably mean PURE/S in resident command.

Sorry, yes that's exactly what I meant.

@thread - oops, I've tried all sorts of other apps as resident using the PURE switch, so far all the continents of Earth are still in place (last time I checked at least).

So give us some examples of programs which are PURE.  (And some which are definitely IMPURE!)

I thought the point of having something resident was not if it was run simutaneously, but if it was run multiple times  to prevent multiple accesses of the same sector on hard drives (or floppies).  For instance,  copying a large amount of files.  Sure you could use a multi-select option or something, but if you're not the disk is accessing the "copy" file each time, thus wearing it out.

That and the speed increase of course.

Or have I misunderstood the purpose of Resident?
