Re: speed(summary) with 86 results

my 86 results with 98K free (basically right out of the box) rom #1.2

For(x,1,1000)
Stop

That prog took less than 1 second to run

0->x
Lbl A
x+1->x
If x<=1000
Goto A
Stop

that prog took my 82 (with 23249 mem free rom number 15) 17  seconds to run
it took my 86 (98K free rom number 1.2) 33 seconds to run (not joking)
