APLSE (APL*PLUS Special Edition): Freeware DOS APL, circa 1992
I believe this is basically APL*PLUS/PC version 10, circa 1992. No Windows, no nested arrays, etc.

To get the APL font, you must maximize your DOS session before running APLFONT.COM; then run APLSE.EXE.

From the file DO_FIRST.TXT:

This product, the APL Special Edition, is freeware. You may use it without charge, copy it, give it to another person, place it on an electronic bulletin board system, or distribute it in other ways without requiring payment from the recipients. Manugistics, Inc., provider of commercial APL products for a variety of platforms, is making this APL Special Edition available to introduce the power of APL and the joys of using this extremely powerful programming language to people who might otherwise never see APL.

Although this product does not have all the features of the newest commercial versions of APL, it is a fully functioning system; it has not been "crippled" in any way. You can do real programming with this system.

To get the APL font to work, I think you must run DOS in Full Screen mode. The following sequence works on my Windows 2000 system:

Open a DOS window

Properties, Options tab, Display Options, Full Screen

C:\APLSE> MODE CON COLS=80 LINES=25
C:\APLSE> APLFONT
C:\APLSE> APLSE
