Names for font family numbers

[Steve Litt]

Hi all,

After working with Philip's font size adjusting routine, I'm left with
the question of \textfont1, \textfont2, and \textfont3.

I know the trailing digits are numbers representing font families, but
I'd like to know what they're called. In a TeX script shown later in
this email, I got the following information:


FROM plain.tex:
itfam: 4
slfam: 5
bffam: 6
ttfam: 7
FROM amssym.tex:
msafam: 8
msbfam: 9
eufmfam: 10
FROM fontch.tex:
mibfam : 11
bsyfam : 12
ssfam : 13
cscfam : 14

So I'm still missing 1,2,3,15, and if they exist, 0 or 16. I grepped
everything in the TeXLive tree for the word newfam, but there were just
too many to thoroughly research. Could somebody please help me out by
telling me the family names for 1, 2, 3, 15, and if they exist, 0 or 16?

The TeX script I used to deduce the preceding name/number mapping
follows:

===================================================
\input eplain
\input amssym
\input fontch

\font\mainfont=cmr10   scaled \magstep3
\mainfont


\vskip 2ex FROM plain.tex:\vskip 0.5ex
itfam: \the\itfam

slfam: \the\slfam

bffam: \the\bffam

ttfam: \the\ttfam

\vskip 2ex FROM amssym.tex:\vskip 0.5ex
msafam: \the\msafam

msbfam: \the\msbfam

eufmfam: \the\eufmfam

\vskip 2ex FROM fontch.tex:\vskip 0.5ex
mibfam :  \the\mibfam 

bsyfam :  \the\bsyfam

ssfam  :  \the\ssfam

cscfam :  \the\cscfam 

\bye
