Combined Filters VZero Line Width Pick 4 The VZero Line Width (VTZ-LW) is a so called "combined filter", a combination of a digit and a math filter. It requires two separate parts to create the filter.
VZero (VTZ) is a different representation of the VTracs (VTX) concept with the difference that the digits start with 0 rather than 1. That simplifies the conversion drastically as the first five digits (0, 1, 2, 3 and 4) are the same in both number and VZero conversion. The Line Width is a so called "math filter". Math filters are created through calculations. The Line Width is the difference between the highest and the lowest digit of a number. To show you how to calculate the VZero Line Width filter for a Pick 4 number here an example step by step.
Part I: Pick 4 VZero Line Width Conversion Step 1: Divide 5711 into separate digits: 5711 => 5 7 1 1 Step 2: Convert each digit to filter: 5 = 0 7 = 2 1 = 1 1 = 1 Step 3: Combine the filters to a string: 0 2 1 1 = 0211
Part II: Pick 4 VZero Line Width Conversion Step 1: Divide the 0211 into separate digits: 0211 => 0 2 1 1 Step 2: Find the highest digit: 0 2 1 1 => 2 Step 3: Find the lowest digit: 2 1 1 0 => 0 Step 4: Subtract the lowest digit from the highest: 2 - 0 = 2
