Notes
The delivery range index is defined in the LensRange.Dat file. It permits differentiated pricing of a product in various power ranges and coating combinations. The delivery range index is part of the key, i.e. different prices can be specified for a product with given diameter and Sph/cyl power in dependence of the delivery range index.
The field “Price of Man. code coatings 1-5 contained in the lens price” in LensRange.Dat indicates whether the coatings defined in the LensRange.Dat file are contained in the lens price.
If only Price 1 and Price 2 are defined (see Head.Dat), the data fields (Price1, Price2 and Price3) can be deleted. As a result, the data set becomes shorter.
The fields 12 and 13 define the validity for a certain period. If two data sets exist which only differ in the validity range, then the data set has priority which has a date entry in one or both fields.
