(or in the configuration file).
To be able to work with TEX practically, apart from the program
itself, you need some additional files. Where these files should
be searched for, can be indicated by environment variables (or in the configuration file).

TEXINPUTS
Where should TEX look for the macro-, the style-files and the text to be
formatted? Here should not forget to include the current directory (to be
indicated as `|.|') in the list. (Files ending in `|tex|', `|sty|')
(Default: ``.,tex:macros'')TEXFORMATS
As mentioned before, to be able to format a text, you need a format file,
in which e.g. the LaTEXmacro package is contained.
(Files ending in `|fmt|')
(Default: ``tex:formats'')
TEXFONTS
TEX additionally needs information about the fonts used, which can be
found in the `TEX Font Metric' files.
(Files ending in `|tfm|')
(Default: ``.,tex:fonts'')
TEXPOOL
initex first reads all strings used in TEX (e.g. error messages)
from a ``Poolfile''.
(File `|tex.pool|')
(Default: ``.,tex:'')
EDITOR
In case there is an error in the input for initex or virtex
(and you are in the interactive mode) you can start an editor with `e'
You can put the name of the editor you want to be called in this variable.
For %s the filename, and
for %d the line number of the error is substituted.
(Default: ``ed %s -i'')
TEXREXX
This variable determines, whether the editor should be started as a system-
command or as an ARexx script. When the variable is not set, the editor is
started as a system command. Does the variable contain an arbitrary string
the editor is not started directly, but an ARexx script is called. Does
TEXREXX now contain the string ``edit'', then, instead of
waiting for the user to start the editor with the e command, it
is started right after the first error occurs.
REXXEDITOR
This variable indicates which ARexx script should be started, in case
the `e' command is given and TEXREXX is set. Normally, this
script is in |rexx:| and has the extension |.rexx|.
(Default: ``texedit %s %d'')
TEXCONFIG
Searchpath for the configuration file |tex.cnf|. Is also possible through
the `-c' option when called.
(File `|tex.cnf|') This variable is also used by the drivers
ShowDVI
and DVIprint. There, however, it can not be a list of paths, but only
a single path.
(Default: ``tex:config'')
