APL-Journal
It turns out that rapid prototyping is perfectly feasible using
scripts, as the scripts can be updated automatically when a
function is edited, if you desire. The really big advantage of
scripts is that third part tools can be brought to bear on APL
systems. The Compare command which has been typed at
the bottom of the previous screen shot produced the following
display:
cost (£50) for non-commercial use. A similar Linux license
will be available in early 2007. Educational users are required
to submit an annual report on the use of Dyalog APL. Noncommercial
use includes experimental use within commercial
organizations: The only restriction on the non-commercial
license is that it not be used to actually run applications
or provide services.
The above screen is being provided by a product called
Compare It!, a $29 download from the Internet. It knows nothing
about APL but is able to compare and merge Unicode
files. Other tools which are immediately applicable to APL
applications in script form are popular source code management
systems like SubVersion. It is thus possible to switch
easily between a dynamic prototyping approach and a controlled
environment.
Educational and Non-commercial Licenses
The object-capable version 11.0 provides an opportunity
to present Dyalog APL to new users in ways which will immediately
appear more familiar to them. In order to make
APL really attractive to new users, it also needs a comprehensive
library of tutorials and code samples – and new educational
materials. We will be working on these in 2007, but
we know that it will take a little time.
We have decided to make Dyalog APL for Windows available
immediately at no cost to educational users – and at low

Other Pricing Changes
We have simplified our pricing, with three goals in mind:
●
●
●
To make it easier and cheaper to get started using APL: The
educational and non-commercial licenses are part of
this strategy, and it is now also significantly cheaper to
buy your first commercial license.
To ensure that successful APL-bases businesses contribute to
investment in APL products and services: All new licenses
have support and upgrades built in. If APL is used to
build applications for resale, or multi-user applications
for internal use in an organization, a run-time license
is required (several pricing models for runtimes are
available).
To bring Windows and Unix pricing into line: The run-time
fee for Windows is part of this strategy; Unix users
have always had to pay for run-time licenses.
