[comp.text.tex] Adding Maths Symbols to TeX/LaTeX

gar@fgp.cltr.uq.oz.au (Greg Restall) (07/30/90)

Dear All,

	I am a logician who is quite enamoured with TeX, but there is
one limitation.   I need more symobls than I have.  So, I get Metafont,
and muck around, and have some workable symbols - my big question is,
how do I get them to work in Math mode properly?  I thought that (in LaTeX),
I could put them in the font lasy, and then the sizing etc is automatic 
when I put relevant \mathchardef 's to access the symbols.  

So, say I have a fishook in character position hex 40, then I'd put
a command \mathchardef\fishook="3A40, in a file that I \input.  
(3 for it being a binary op, A as lasy is family A, and 40 is the code.)
Alas, this doesn't work.  I know the character is in the file lasy10.tfm
and also the pk files (I ran fontsample.tex, and they showed up.)

So, what gives?  Is there another way?  Should my extra symbols reside
in a different file?  (lasy has plenty of room - why not in there?)
What I want to know is how to get them to act properly in math mode,
with all the resizing etc. ok.  Preferably both in TeX and LaTeX,
as I use both.   I've read the TeXbook, but it seems quite opaque
on adding extra mathematical symbols, so if anyone could help, I'd
appreciate the assistance.
