Re: CPU usage of FNget?

Grahame Pratt

Ah, thanks!  I should obviously have opened up NOWAIT and looked for myself (I think I just assumed that Fnget was some assembly language which I would not understand). Sorry for that.

Yes, "Too little to care about". Works for me.

It uses some, of course, because it's actively executing code (principally the INKEY function) approximately once every millisecond:

SYS "Sleep",1
K% = INKEY(0)
UNTIL K%<>-1

But it wouldn't be very easy to measure accurately *how* much because it will be below the threshold necessary for Task Manager to indicate anything (0.1%).

Why do you care, so long as it's 'too little to matter'?
