NOTE: These programs should compile and execute properly
using the GNAT Ada compiler and development environment.
This is the prevalent current Ada development system, and
is available as a free download, distributed under the GNU
General Public License, from http://libre.adacore.com.
Windows, Linux, and Mac OS X implementations are
available.
The Spider package and associated examples will compile
under all implementations. The resulting executable
programs will behave properly under Mac OS X and Linux.
Spider programs will probably not look correct when
executed on Windows computers. The Spider package depends
for cursor placement upon a Windows system file called
ANSI.SYS, which Microsoft appears to have discontinued in
recent Windows versions. I have tried unsuccessfully to
find a suitable substitute.
