I recommend the programmer read the document Inside CartOff EBook, available for free as part of the CartOff SourceForge download cartoff-1.1.zip (<drive>:\CT\CartOff\EBook.zip). The document provides the essential information about projections and datums and specifically how they relate to CartOff so that you can get the desired results without a lengthy learning or trial-and-error period. Plus it is loaded with full information about CartOff.

A utility is included with the EBook to export as text the coordinates of vertices in a shapefile.  This assists the programmer in validating results of CartOff by comparing the results to equivalent workflows in ArcView.
