     I have downloaded the PICC-Lite series and feel it well.Because I have just use C in PIC's program only few days.I have a problem in getch( ).In the PICC-Lite's include file,I have found the prototype of getch( ).This function I know is answer the input of keyboard in ANSI C.In PIC's peripheral hardware,the key's position is not fixation.So I think the getch( ) we must be implement oneself,But why it supply a prototype in its include file?
