I am using four different fonts in the same document. Three
of them are the run-of-the-mill roman, italic and bold which
are loaded in positions 1 2 and 3. I want to refer to the
fourth font in a generic manner, in such way that I can
print the document in different typesetters without having
to do major editings in the document. I will alternate
between a PostScript laser and an APS typesetter. Since,
similar fonts have different designations in the two
printers, if I use the escape sequence "\fxx" to change
fonts, I have will to edit every occurrence of that string
when I change printers.
I tried to load the extra font in a preselected posi-
tion with the troff command
.fp 4 xx
Troff gives an error message:
"font xx is to big for position 4"
Apparently (according to the local troff guru) ".fp" behaves
differently from machine to machine.
How do I assign symbolic names to fonts in the begin-
ning of the document? Any suggestions?wnp@dcs.UUCP (Wolf N. Paul) (02/22/88)

Apparently TROFF knows how many characters ought to be in that font and burps if that does not match reality. If that is so, mounting a font other than "S" in fp 4 is likely to give strange results, even if TROFF let you mount it. -- Wolf N.

That is, font xx has more characters than font 4. The space troff has allocated for 4 is too small to hold xx. This problem existed in older Troff's -- it's fixed in DWB 2.0. If you have DWB 2.0 source, look at "biggestfont" in your DESC file and make it as big as any font you have (or 255 if you feel like wasting memory.) If you don't have DWB 2.0, trying mounting xx at another position. -- Ken Greer Elan Computer Group, Inc. 415-322-2450 {ames,hplabs}!elan!kg

If you want to assign symbolic names to troff fonts, you can use a troff
string define IF you have device-independent troff. You will need to test
the value of the .T string and define the string accordingly. At our site,
we have a Dataproducts PostScript printer and an Imagen. I use this code to
handle the different names for the Courier font:
.\" Ef is example font (Courier), which is used in code displays.
.\" If the string .T is 300, we are on the Imagen and Courier is L.
.\" If the string .T is psc, we are on the Dataproducts and it is C.
.if t .if '\*(.T'300' .ds Ef L
.if t .if '\*(.T'psc' .ds Ef C
.DS
\f\*(Ef
main(argv, argc)
.
.
\fR
.DE
Remember that this works only for device-independent troff.
