Library /sys$common/syshlp/dbg$help.hlb DEBUG, EDIT, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    If you have not specified an editor with the SET EDITOR command,
    the EDIT command starts the DEC Language-Sensitive Editor
    (LSEDIT) in a spawned subprocess (if LSEDIT is installed on your
    system). The typical (default) way to use the EDIT command is
    not to specify any parameters. In this case, the editing cursor
    is initially positioned at the beginning of the line that is
    centered in the currently selected debugger source display (the
    current source display).

    The SET EDITOR command provides options for starting different
    editors, either in a subprocess or through a callable interface.
