By default, TPC assumes that the first word in the description is a code. Anything that follows the first word is just part of the description or attribute and can be used to provide information about the point.
Additional codes can be placed in the description or attribute by preceding them with the 'code delimiter'. TPC uses two dashes '--' as its default code delimiter. You can embed as many codes as you like using code delimiters as in 'TFC--CB--SW' which includes the codes TFC, CB and SW.
If the description starts with the code delimiter, the code delimiter is ignored, so the point description '--CL--SD' will produce the same two codes (CL and SD) as the point description 'CL--SD'.
Any point that has multiple codes in its description can be sorted into traverses for each of the codes. This gives you the ability to sort an OAK--TREE into both the Oak traverse and the Tree traverse for example. You may find many uses for this feature.
