Library /sys$common/syshlp/edthelp.hlb CHANGE, SUBCOMMANDS, TOP  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 The TOP command forces the line on which the cursor is positioned to the
 top of the screen.  If there is less than a full screen of lines between
 the current line and the end of the buffer, TOP has no effect.
