[foxboro] Increment Values

Hi Group.

I want change the value of an given C:B.P.
The value should change up/down from current value.
For example in +/-0.5 steps   (newvalue =3D oldvalue + 0.5)

The ramp function isn't the right function. Because the C:B.P increase
by percent of the control range.

Has anybody an easy solution for this small problem?

Dirk
