Yeah, I also use APL2/PC ver 1.02 - acquired summer of
93 and used ever since.

I had same problem when installing APL2/PC on my 486DX
(along with a variety of other problems  - especially with
EMM386 active).  Invoking APL2FONT.COM without any
switches turned my VGA monitor into a "black hole" and
also locked the machine up real tight - cold boot needed to

Back then, I did considerable experimentation with
APL2FONT.COM and the batch file APLON.BAT.
The latter provided code page switching examples that,
after some changes  - both rewriting and renaming APLON
as well as modifying CONFIG.SYS (activating DISPLAY.SYS)
seemed to provide the most reliable way to run APL2.
I just gave up on APL2FONT as too unreliable.  See
later comment.

After your post I went back and experimented again with
APL2FONT with the B, S, and T switches.  B alone
usually worked, but occasionally brought APL2 up with
odd looking "split" lines on my VGA.   T always worked,
S worked maybe 60-70% of time.  When it failed the
machine locked up and screen went black, cold boot
required.  When it worked, the small font appeared, but
like your experience, without  APL glyphs. H switch
locked machine.

You might take a look at WSs FONTEDIT and FONTUTIL and
their writeups in Vol I of the 3 ring binder manual,
There is discussion of how to modify APL2FONT.COM.
I tried it, still no luck with /S  - The "weirdness" remains!

Recommendations - Just refuse to mess with APL2FONT.
Instead start APL2 with batch files that use "mode" and
"chcp" commands.  Unfortunately this means living
with the large 25 line APL font.

Re EMM386 and DISPLAY.SYS, I use DOS 6.2 with a
menu setup in CONFIG that boots up 3 options -
(1)do not run APL2 (2)run APL2 from DOS
command line, (3)run APL2 under Windows 3.1.
