Section 001 is where we program the zone definitions for the first sixteen zones. Before programming zone one we need to assemble a zone defintion string made up of two digit definitions, in order, from zone one to the last zone we intend to use in our system. Keep in mind that a PC1616 only has six hardwire zones before going into wireless zones, a PC1832 or PC1864 has eight. So for a PC1616 not using wireless the maximum string will be 12 digits long, a PC1832 without wireless will be 16 digits.  Our first step is to assemble our zone definition string.
