I am having some trouble using ArbourText's LaTeX.
I am using LaTeX Version 2.09 <4 Aug 1988>
with TeX version 2.9.16.1, running under Sun UNIX 4.2 Release 3.5.
My shell is csh.

I wish to use my own style files and keep them in my own inputs directory.
man TeX tells me I can set the environment variable TEXINPUTS to a search
path including my inputs directory for style files.
ArborText's documentation says the same thing except the variable is called
TEX_INPUTS.
Unfortunately neither one seems to do anything.
Even if I set them to not go though the normal input directories LaTeX can
still find the normal style files, but not mine.
I know my style file is ok because if a a copy is in the directory in which
I am working, or if I give its the full path name as the style files name, then
I have no problems.

Can anyone help me on this?
