connect sequential Q parameters with a hyphen,
e.g. 1,3,200-208. The input range per parameter
type is 132 characters
The display in the QPARA tab always contains eight
decimal places. The result of Q1 = COS89.999 is
shown by the control as 0.00001745, for example.
Very large or very small values are displayed by
the control in exponential notation. The result of
Q1 = COS 89.999 * 0.001 is shown by the control as
+1.74532925e-08, whereby e-08 corresponds to the
factor of 10 -8
