Mid$ slow

BlitzPlus Forums/BlitzPlus Programming/Mid$ slow

Is possible that Mid$ command is really slow ? anyone try to make a long cicle with mid$ command inside ? try this stupid source to test it:

Temp$="try"
Tim=millisecs()
for i=1 to 9999999
a$=mid$(Temp$,1,1)
next
print millisecs()-Tim
input

is only mine problem ? there are some other solution to make a mid$(string,start,lenght) at more fast speed ?
