Messung von 2000000 For-Next - Statents
----------------------------------------
Pro Sekunde:      268592
Gesamtlaufzeit:   7.446217
> option list
OPTION KEYBOARD GR
OPTION CPUSPEED (KHz) 378000
OPTION SDCARD GP10, GP12, GP11, GP13
OPTION AUDIO GP6,GP7, ON PWM CHANNEL 3

with OPTION CPUSPEED 378000
~ half as fast as cmm2


Print "Messung von 2000000 For-Next - Statents"
Print "----------------------------------------"
t%=Timer
For f%=1 To 2000000
Next f%
l= Timer-t%
Print "Pro Sekunde:     ";Int(2000000/(l/1000))
Print "Gesamtlaufzeit:  "l /1000




a littlie faster, if I put the Next statement in the same Line as the For Statement :

Messung von 2000000 For-Next - Statents
----------------------------------------
Pro Sekunde:      275513
Gesamtlaufzeit:   7.259177

but .. if I delete the Variable behind the NEXT Statement

Messung von 2000000 For-Next - Statents
----------------------------------------
Pro Sekunde:      589522
Gesamtlaufzeit:   3.392575
 

Print "Messung von 2000000 For-Next - Statents"
Print "----------------------------------------"
t%=Timer
For f%=1 To 2000000:Next
l= Timer-t%
Print "Pro Sekunde:     ";Int(2000000/(l/1000))
Print "Gesamtlaufzeit:  "l /1000



the question remains, how meaningful such test results are
