Range specifications

A range specifier takes the form of 'a, b, c' where each of the values 'a', 'b' and 'c' represent real numbers and it is interpreted as from 'a' to 'b' in steps of 'c'. The value 'c' is optional and if it is not present then a step size of 1 is assumed. The value 'b' is also optional and if it is not present then 'a' defines a single value. Ranges can be made complex by concatenating ranges together using the ';' character. Thus a complex range may take the form, '1,9,2;20,100,10'.

Desc field number

The entry in this field has no effect for this function.
