** ^FILE: pgopen.h - include file for pgopen.c
**
** ^DESCRIPTION:
**    If USE_PAGER is #define'd then this file will define the function
**    prototypes needed to use the paging library implemented in pgopen.c;
**    Otherwise it will #define macros with the same name as the paging
**    library routines which do NOT perform any paging.
