        MswLogo Version 2.4 for Micro-Soft Windows 3.X is ready !!!
        ------------------------------------------------------------

NOTE: ZIP naming convention has slight change !!!

LOCATION: itrc::/millspub/mswlgo24.zip (this is a DEC internal location)
            or
          cher.media.mit.edu on pub/comp.lang.logo/programs/mswlogo
            or
          Send the following message to: ftpmail@decwrl.dec.com 
----cut here----
connect 18.85.0.47

chdir pub/comp.lang.logo/programs/mswlogo
get mswlgo24.zip
quit

Note: There is no connection between the ftpmail server suggested here
and cher.media.mit.edu or MswLogo. It is a common service to internet
users from Digital Equipment Corporation. There are other ftpmailers
available but I don't know the addresses.

New features/bugs fixed:

   o MCI (MultiMedia) support. See help on the logo MCI command first.
     Also try the VERY simple examples "echo" and "sounds" in the library.
     I don't have a MIDI or CDROM (yet :-)) but that should all work also.
     Note, also windows 3.1 supplied MIDI driver cannot record but I believe
     MIDI hardware venders supply one that does.

   o New LOGO commands
        - bitload, bitsave (same as menu commands).
        - block (draws filled rectangles).
        - See mkmod, rmmod, pushmod, and popmod commands below.

   o Fixed LOGO commands
        - Pots command finally works and shows procedures and modules.
        - help (calls help).
        - describe (jumps directly to keyword in help).

   o Online Help is cleaned up a lot.
        - status, nostatus (same as button) command was missing.
        - char command was missing.
        - int and round command was missing.
        - gprop command was missing.

   o Logo now has the concept of "modules" (all done through directories).
     See mkmod, rmmod, pushmod, and popmod commands. Note users can only
     create or delete "Logo components (.lg and .lgo)". And only at the
     directory level in which logo started at or lower.

   o The "stack" area is much larger now and you can make recursive calls
     much deeper than before.

   o Fixed overpowered focus on commander. It won't jump on top of the editor.

   o Trace button finally works.

   o Fixed jagged turtle again, and it is really fixed this time :-).

NOTE: Windows 3.0 users there is a seperate executable for 3.0
      due to the MultiMedia enhancements which 3.0 does not have.

To Install it:

1) UnZip MSWLGO24.ZIP into a directory (e.g. c:\logo)

2) UnZip LOGOLIB.ZIP (included in MSWLGO24.ZIP) into LIB (e.g. c:\logo\lib)

   Note:  If you do not use c:\logo as the root you must set the
          environment variable LOGOPATH to where you put it (e.g.
          set logopath=d:\games\logo in autoexec.bat)

3) Copy BWCC.DLL (included in the .ZIP) to anywhere in your PATH.
   This could be where you place LOGO (as long as it's in your PATH).
   When I say PATH here I don't mean LOGOPATH. The desired place is
   in your root windows directory (e.g. c:\windows).   

4) Start Windows and add an Icon as follows:

   a) Select the applications (or other) group box.

   b) Go into Program manger FILE menu and click on New.

   c) Select Program Item and click OK.

   d) Enter the command for logo (e.g. c:\logo\logo).
      Windows 3.0 users MUST use logo30 (e.g. c:\logo\logo30).

      This can also be where you select the size of the image (NOT the size
      window). The switches "-h number" (to select height) and "-w number" (to
      select width). The default has been and still is 1000x1000. For example
      to change to a 500x500 image (using 1/4 the amount of memory) enter:

      c:\logo\logo -h 500 -w 500

   e) Include a working directory (e.g. c:\logo\work) or you'll have ".lg"
      files all over the place (this applies to 3.1 only). I'll try to come
      up with a better solution soon.

Start it from Windows by double clicking the Logo Icon

Start it from DOS by typing "win logo [options]" at DOS prompt (assuming
logo.exe is in your PATH).

Try typing "DEMO" in the "Input Box" (out of bounds at end of demo is normal).
Note: "DEMO" is a logo program in the library, it's not an internal command.

Standard features:

   o Supports Text.
   o Supports color palette (256 solid colors).
   o Cut and Paste.
   o Floodfill.
   o penwidth.
   o Save and restore images in .BMP format.
   o screencolor (background).
   o 16.7 million pen and background colors (using windows dithering).
   o Standard Windows Hypertext Help.
   o Standard Windows Printing.
   o Supports separate library and work area.

Bugs / Basic Missing features:

   o Real mode is not supported.
   o goodbye still not working.
   o printing on (very few) printers still doesn't work.
   o Need to make save/restore image smarter (less memory, disk and cpu).
   o Need arrow-key command recall.

   o If a bug is really bugging you or feature you really want to see done,
     say so, by sending me email. This will help me determine what's important.
     No promises, but it will help. I love any feedback good or bad.

Trouble shooting:

   o Logo accesses the disk everytime it draws a square in the DEMO
     (part 3). This is related to your buffers command in config.sys
     buffers=20 or more is typical for a "windows environment". 

   o Logo seems to run extremly slow and the disk is always thrashing.
     Your probably paging. You may be running with 256 color driver
     with out the memory to support it. Try 16 color mode or reduce the
     image size (or both).

   o Loading in an .BMP does not seem to have the right colors.
     If you had been using logo for a while you probably have used up
     part of the color palette. It's not a bad idea to clear the palette
     before loading in a .BMP.

Wish list:

   o Sound generation.
   o Clipboard support.
   o Multiple Turtles.

The Core of this Version of Logo comes from a project done by Boston Childrens
Museum and Lincoln Sudbury Regonal High School. The Port to Windows was done
by George Mills Digital Equipment Corporation. Digital Equipment Corporation
takes no responsibility for the software.

There is also a DOS version (with out the added functionality added to MswLOGO)
is available. Same location as MswLOGO.
