In the case study, the XYZ company has a separate vector for each application. Using VDN variables, the company can consolidate similar vectors that are each reached by a different VDN, into one vector. The company plans to use the newly-freed vectors for other applications. The problem is that the number of different parameters or values required to be assigned to the VDNs as VDN variables exceeds the limit of five variables.

The case study shows a method for combining parameter values into digit strings of up to 16 digits. Each digit string can be assigned to the VDN variables, separated into the component parts and assigned to vector variables in the common vector for each of the vector commands.
