On Wednesday, 3 Apr 1996, Zdenek V Jizba
announced the beginning of work on a series
tutorials for APL2 running under OS2.
One of my ongoing projects over the past few years has been the
writing of interactive tutorials on APL. Most recently I have
been upgrading the tutorials on APL2 (PC version) to the APL2OS2
version. This has turned out to be a bigger task than expected.
OS2 and APL2OS2 are so intertwined that to learn how to use
effectively APL2 requires familiarity with OS/2. Furthermore, the
auxiliary processors of APL2OS2 have been changed so much that my
previous tutorial workspaces have to be practically re-written.
As of now there are seven APL2OS2 tutorial workspaces more or
less in a state of completion (though I find it necessary on
occasion to update them on the basis of my ever increasing
knowledge of OS2).
In the October of 1997, Denny polished off a new series of 22 Tutorials,
complete with a
file, an Index workspace, and a Utility workspace.
download all 25 of these,
the READ.ME file and 24 workspaces, all in one package.
The original package planned for eight tutorials for this series, but
it has since grown.
Whatever else appears in the future

While developping workspace TEACH52 the command SETPEL
ceased to operate. Possibly because of this, during the final
editing of workspace TEACH51 some anomalous effects were
observed. All efforts to correct the problem have so far failed.
Regretfully I am suspending indefinitely all further work on
- TEACH52 Not yet available
The POINT command. Rubber band interaction with the
graphic screen. SETPEL and SCISSOR.(This workspace is
still under development.)
