I have placed a new release of my aXe editor in aXe-5.0.tar.Z on export.lcs.mit.edu (18.24.0.12) and arjuna.ncl.ac.uk (128.240.150.1).  The significant change this time, and the justification for the hike in the major version number, is:    o undo has been implemented.      By default only the last change can be undone, but a resource is     provided to allow the user to specify how many, including unlimited,     levels of undo information should be kept. Also, undo of undo is     supported.  There is no truth in the rumour that the next version will be EmaXe 19 :-)                            -=-=-=-=-=-=-=-=-=-  For those who have not encountered aXe before here is a summary of what it is all about:  aXe is a simple to use text editor for X that represents a significant improvement over xedit. Also built around the Athena Text Widget it features, amongst other things,     o multiple windows    o multiple buffers    o default menu interface    o optional button interface, with choice and layout of buttons       under user control    o minibuffer for expert use and access to external filters    o provision for defining a keyboard macro    o geometry specification and resizing in terms of characters    o file selection via a browser    o knowledge of line numbers    o parenthesis matching    o regular expression searching    o restricted or unlimited undo    o ability to change font    o easy entry of control codes    o xterm-like keymap feature    o easy runtime setting of selected preferences (resources)    o both brief and comprehensive on-line help    o server mode with cooperating client programs    o optional extension language using Tcl    o optional Xaw3d widget set compatability    o collection of reusable widgets that embody the functionality of aXe  I have personally built and run core aXe, i.e. without the Tcl and Xaw3d options, on the following systems:     Sun SPARC        SunOS 4.1.x     MIT X11R5    Sun SPARC        SunOS 5.1       MIT X11R5    Encore Multimax  UMAX 4.3        MIT X11R5    DEC 5000/120     ULTRIX 4.2      MIT X11R5    HP 9000/710      HP-UX 8.07      MIT X11R5    MAC IIci         AU/X 3.0        MIT X11R5     but not all have been subject to the same level of testing. I have only tested the Tcl and Xaw3d options on the first.  A number of '#ifdef SYSV'-isms that have been fed back to me have been incorporated into the code and a possible scandir replacement is provided for those systems that do not have one.  Although aXe will probably build under R4 run-time problems have been encountered in the past. I have not bothered to try this version under R4, and have not put any effort into solving previously known problems.  Therefore, if you are at R4 you very much take pot luck. If it doesn't work the only alternative is to try the last release, 2.1.1, of version 2 which should still be around. It doesn't have as many features and uses the Widget Creation Library (Wcl). Not only that, it requires an old version of Wcl, 1.06 or 1.05. Version 3 of aXe was nearing completion when version 2 of Wcl came out so aXe 2 never got converted to make use of it.  aXe is available by anonymous ftp from export.lcs.mit.edu (18.24.0.12) and arjuna.ncl.ac.uk (128.240.150.1) initially, and probably in due course from several other ftp sites.  Check your nearest using xarchie.  If you can't ftp, try sending email to ftpmail@decwrl.dec.com with the word "help" alone in your message body.  You will receive instructions on how to ftp via email.  Jim
