[comp.text.tex] emTeX .DVI driver quirks?!

DLV101@psuvm.psu.edu (Dwaine VanBibber) (10/07/90)

Hi all! I've got a couple questions regarding the DVI drivers supplied with
emTeX. First, has anyone else noticed that the drivers conduct a case sensitive
search for fonts? (ie, \font\thefont\CMBX10 is reported to be not found)
Should this be considered a bug given that MS-DOS does not have a case
sensitive file system? I have not yet experimented with font names greater
than 8 characters, but it might be interesting.

Lastly, has anyone played around with dvihplj version 1.4b or later? With
prior versions I was able to print envelopes using a modified version of
Knuth's letter macro and the following command line switches: /b0 /e0 /l=1.5in
/t=0cm. For this the printer was in landscape mode. With version 1.4b, however,
I am receiving a lot of "overstriking" and utter garbage. Any suggestions?
Someone in the os2.binaries is having a similar problem, I believe.

Thanks,
Dwaine

Yes, I did!

Since DOS doesn't care about the case of a filename, I would not consider
it a bug. It's going to be more of a problem when you yourselves uses a
fontpath in Uppercase, and then take it to a Unix box. Here it'll stall,
but then Unix is case-sensitive.
EmTeX does have a 'problem' with font names longer then 8 chars:
like circlew10. Here the last '0' get left out, but it does end up in the
packed li. I've not yet come across any problems with this, so my guess
is the Ebenhart Mattes is aware op possible problems in this field.

Happy {Em}TeXing,

Font names are case-sensitive only in font *libraries*, not in font
*files*. Font names are truncated to 8 characters when using font
files or the old font library format (dvidrv 1.4c or older; see
fontlib.doc). Font names are *not* truncated in new font libraries
(dvidrv 1.4d or later).
