    24Hemlock is a text editor which follows in the tradition of Emacs and the Lisp Machine editor ZWEI.  In its basic

     472== 1.11 Entering and Exiting ==
    471473 Hemlock is entered by using the COMMON LISP ed function. Simply typing (ed )will enter Hemlock , leaving
    472474you in the state that you were in when you left it.  If Hemlock has never been entered before then the current buffer

    526 == 1.13. Recursive Edits ==
     528== 1.13 Recursive Edits ==
    527529Some sophisticated commands, such as Query Replace, can place you in a recursive edit. A recursive edit is
    528530simply a recursive invocation of  Hemlock done within a command.  A recursive edit is useful because it allows
     
    542544edit, this signals an user error.

    544 == 1.14. User Errors ==
     546== 1.14 User Errors ==
    545547When in the course of editing,  Hemlock is unable to do what it thinks you want to do, then it brings this to your
    546548attention by a beep or a screen flash (possibly accompanied by an explanatory echo area message such as
     
    552554complained to do what you wanted it to do.
    553555
    554 == 1.15. Internal Errors ==
     556== 1.15 Internal Errors ==
    555557A message of this form may appear in the echo area, accompanied by a beep:
    556558{{{
     
    562564{{{
    563565Internal error:
    564 No access to "/lisp2/ Emacs /teco.mid"
     566No access to "/lisp2/Emacs/teco.mid"
    565567}}}
    566568Otherwise, you have found a bug.  Try to avoid the behavior that resulted in the error and report the problem to your system maintainer.  Since LISP has fairly robust error recovery mechanisms, probably no damage has been done.
