Introduction
------------
Yorick is a tool for analyzing numerical data. It has an interpreter
that uses a C-like language and can operate on entire arrays without
any need for do loops over the array indices. Yorick has a file I/O
package with the ability to conveniently read text files with
columns of numbers. The file I/O package can easily be trained to
read a wide variety of binary and text files, if the formatting
rules for the file are known. Yorick has a 2D graphics package that
includes polylines, contour plots, cell arrays, and filled mesh
plots. The new 3D graphics package provides surface plots, slicing
planes, and iso-surfaces.
Gist is a program that displays frames in binary CGM files written by
yorick and other applications (e.g. ATC GKS, IDL). gist is
particularly useful for making PICT files from a CGM file written by
a Unix version of yorick.
Macintosh versions of Yorick and Gist are labeled by the version
number of the corresponding Unix release followed by the Mac version.
For example, version 1.2v1 means the first version based on Unix
release 1.2.
Bug fixes and New Features in release 1.2vr1
--------------------------------------------
macyorick has all the bug fixes in the 1.2 release of yorick for Unix
plus fixes for the first two bugs found in release 1.2.
Previous versions of macyorick did not correctly display polygons
with more than 98 vertices. The new limit should be large enough
that you will never encounter it.
When yorick detects a syntax error in an include file, it should
correctly load the file into a text editor and put the cursor on the
offending line. Previous versions did not behave correctly when a
text editor was already open at the time they tried to open the file
with the error in it.
New features include a 3D graphics package, a list processing package,
and the catch function.
Getting Yorick and Gist
-----------------------
Yorick is distributed in several self-extracting archive files. There
is a version that runs on any 68020, 68030, or 68040 Mac with a
floating point chip (FPU), another version that runs on 68020, 68030,
or 68040 Macs without an FPU (e.g. 68040LC), and a Power Mac version.
There is also a PowerMac version of gist and a 68000 version that
does not require an FPU. Each version of gist and yorick checks for
the Mac hardware and software it requires and aborts if it is not
found (it is possible that detection of old 68000 Macs does not
work).
If you can do so, download the "sea" file in MacBinary mode with your
ftp program. If the ftp site you are using only has the "hqx"
version, download it and use a program like UnStuffIt to decode the
BinHex file. Once you have the "sea" file, double-click on it and it
will automatically split itself apart into the constituent files.
You can also subscribe to the Yorick mailing list by sending the message
subscribe yorick
(in the *body* of the message, *not* the Subject: header) to
majordomo@lists.llnl.gov
If you have some question, comment, or Yorick source code you think
might be valuable to other Yorick users, you may post it to all the
subscribers by sending it to
yorick@llnl.gov
(Questions you don't want to ask publically - and all installation
problems - should still go to munro@icf.llnl.gov, or to shl@icf.llnl.gov
if they are Mac specific.)
