David,
Look at swkey.h
If you have the correct version you will find:
/**********************************/
#ifdef __VCBUILD__
class SW_POSITION {
char pos;
public:
SW_POSITION(char ipos) { pos = ipos; }
operator char() { return pos; }
};
#define POSITION SW_POSITION
#endif
/**********************************/
If you don't have the correct version let me know.
