I just borrowed a copy of Experlogo and I'm posting a microreview
Good Points:
This Logo has most of the meaty functions from a real Lisp. It includes
lots of array stuff, properties and even FUNCALL.
The user interface is fairly nice, with an editor window and a listener
window. Applications may make multiple graphics windows.
There is support for the quickdraw graphics part of the tool box.
Bunny graphics support is a faster version of the turtle in most LOGOS,
but these bunnies can be 3d and mapped to a sphere. (Good for maps and
such).
Code runs very fast.
Bad Points:
Error messages are cryptic
Apparently 128K macs can get GC problems.
Math Routines are not bullet-proof (Try incrementing an integer past
32768!)
The compilation phase is slow (the first time you run some code).
Overall: I really like it so far, except for some speed issues.
(The program does take an extra chunk of time to run the first time --
it's building a memory map of some sort.) The true LISP part is pretty
nice, but I wish they had simply ignored MACLISP syntax when they borrowed
functions.(RPLACA should have been set-first, or somesuch). The price is
right and they encourage you to make (2) copies for your own use.
Copy protection is a "validate-once" scheme!
I'll try to put some real code in this weekend, but for $129 (list)
this could be a real bargain (for a 512K Mac -- 128K Macs do have \
memory problems.) This program doesn't compile final applications (no
menu bars, etc.) but it is pretty spiffy.
Wait 'til I can beat on it,
