NAME
        PathPart -- Returns a pointer to the end of the next-to-last (V36)
                    component of a path.

   SYNOPSIS
        fileptr = PathPart( path )
        D0                   D1

        strptr pathpart( strptr )

   FUNCTION
        This function returns a pointer to the character after the next-to-last
        component of a path specification, which will normally be the directory
        name.  If there is only one component, it returns a pointer to the
        beginning of the string.  The only real difference between this and
        filepart() is the handling of '/'.

   INPUTS
        path - pointer to an path string.  May be relative to the current
               directory or the current disk.

   RESULT
        fileptr - pointer to the end of the next-to-last component of the path.

   EXAMPLE
        PathPart("xxx:yyy/zzz/qqq") would return a pointer to the last '/'.
        PathPart("xxx:yyy") would return a pointer to the first 'y').
