I've been reading this newsgroup for quite some time now, but I've never
posted before.  Here we go...

In reference to your <<other stuff...>> inside the awk program, I am
assuming that you are talking about more awk statements.  The problem
is that only one output statement to a pipe is permitted in an awk
program.  The solution that I see is to pipe your translated text into
an awk program:
	cat filename | tr [a-z] [A-Z] | awk '<<other stuff...>>'

I hope this helps!
