It would make more sense to just use motor(1,speed*14)
This would give you the following:
Value --> Speed
0 --> 0
1 --> 14
2 --> 28
3 --> 42
4 --> 56
5 --> 70
6 --> 84
7 --> 98
I wouldn't bother rewriting the routine.

| (...) Depends on how far you wish IC to go. Someday there could be another controller that allows 100 disrete levels. On the other hand that could be handled well by allowing the value to go to 100, and the code written to go to 8 would be kinda (...) (29 years ago, 18-Mar-96, to lugnet.robotics.handyboard)
