I worked with eqn quite a lot in troff days of past-not-so-perfect. It
was rather easy to use.
Now I try my luck with groff's eqn and can't get anything going.
A simple groff program like this:
.EQ
x = y + z
.EN
.ex
indicates a syntax error. No matter what is between .EQ and .EN, it is
syntax error.
If I .so e.tmac (where definitions of .EQ and EN are?), it does not
matter.
If I use eqn alone or via `groff -set -I ...', the result is the same.
The $...$ inline thing is not working either.
Certainly I missed something fundamental, but I can't figure it out
what.
Please help,
Miklos
PS: I run version 1.19.2
