- This is the first Amiga release of Berkeley Logo, or UCB Logo as it's also
- known. The orginal, multi-platform version was written in portable C code
- by Brian Harvey <bh@anarres.cs.berkeley.edu>, author of the classic book
- series, "Computer Science Logo Style". The code was ported to the Amiga
- by Andy Philpotts <xyzzy@nando.net> and further tarted up by Tony Belding
- <tlbelding@htcomp.net>.
-
- There are two executables in this release. The one called "LOGO.68000" is
- for any Amiga, but will not produce maximum speed on advanced processors.
- The program "LOGO.68040" requires a 68040 CPU, and should give far better
- performance on the Amiga 4000 or other '040 accelerated Amigas. Both
- versions require OS 2.04 or higher, due to the use of public screens.
-
- By default, Logo opens two windows on the Workbench (or current default
- public screen, actually). One is the text console, and the other is the
- turtle graphics area. If you have the excellent ScreenWizard utility (by
- Raymond Penners, available through AmiNet), you can cause Logo to open its
- own public screen with characteristics of your choice. I have tried it on
- a Picasso II 640x480 screen and it worked nicely. Just define your screen
- with ScreenWizard and give it the public name LOGO. When used this way,
- Logo will create a backdrop window for the turtle, giving it the whole
- screen area to play on.
-
- WHAT'S IT GOOD FOR?
-
- I'm glad you asked. This current release conforms closely to the standard
- MIT, UBC and related Logos found on other platforms, so it's a good
- vehicle for exploring the language or turtle graphics (or both). It's
- also a proven educational tool for teaching programming and geometry
- concepts to young people.
-
- It is NOT currently suited for use as a general-purpose Amiga programming
- language. It lacks the primitives needed to access the Amiga system in a
- flexible way.
-
- If you are interested in applying Logo to a wider usage, I am happy to
- suggest PowerLOGO by Gary Teachout. It is a more non-standard (but more
- powerful and flexible) dialect of Logo with many facilities for accessing
- the Amiga's environment. As I write this (July 1996), PowerLOGO 1.4 is
- being posted to AmiNet, and work is underway on PowerLOGO 1.5.
