[MiKTeX] user tex directory input

[David A S. <das...@um...>]

Dear miktex-users,

I am a new user of miktex, with winedt on a Windows PC.  I cannot figure
out how to specify a directory for miktex latex to search through in order
to find my file: mymacros.tex which I bring in my .tex with a
\input{mymacros.tex} command.  It seems I must add a path to the
miktex.ini file, and make a copy of the file in a different directory?

So far I am explicitly doing
\input{d:/d/math/mymacros.tex}

best,

David Schneider
