Enhancements to Graph It in Action

Before using Enhancements to Graph It, you must first merge the supplied program changes with your copy of the original Graph It BASIC programs.  Once merged and saved to a new diskette that is created as part of the process, you boot the new diskette.  Unlike Graph-It, Enhancements to Graph It equips you with a menu for easy selection.
