The VALUEMIN attribute defines a lower limit of values displayed in widgets (such as progress bars).
VALUEMIN = integer
This attribute is typically used to define the lower limit in PROGRESSBAR, SPINEDIT and SLIDER fields.
This attribute is not used by the runtime system to validate the field. You must use the INCLUDE attribute to control value boundaries.
SLIDER s01 = FORMONLY.slider01, VALUEMIN=0, VALUEMAX=500;
