The RC Structure
The core of the recognition process in version 1.0 was the RC data structure. The structure still exists in version 2.0, but it is made obsolete by the HRC object that governs the recognition process. An application can still use an RC structure when calling the obsolete version 1.0 functions ProcessWriting, InitRC, Recognize, and RecognizeData. The following table lists the members of the RC structure. For each member, the second column describes the corresponding services in version 2.0 of the Pen API. Use this table to update your version 1.0 applications to use the new services. See the reference chapters in Part 2 for descriptions of the functions, messages, and constants cited in the table.| RC member
