peekb()                  Examine Memory Location

 #include   <dos.h>

 char       peek(segment,offset);
 int        segment;                     Segment
 unsigned   offset;                      Offset

    peekb() examines the memory location addressed by 'segment:offset'.

    Returns:    The value stored at the memory location 'segment:offset'.
                A byte is returned.

      Notes:    If <dos.h> is included, peekb() is treated as a macro.
                If <dos.h> is not included or #undef is used on it, the
                function peekb() will be used.
