--- Comment #2 from Dave Cottlehuber <dch@freebsd.org> ---
Lari this is because you're not using `erl -s ..` correctly. This is covered in
the manpage http://erlang.org/doc/man/erl.html but you kinda need to know what
you're looking at first.

-s takes a module name (guardseq) not a filename.

$ erl -noshell -s guardseq start -s init stop

I'd normally test this via shell:

$ erl
Erlang/OTP 24 [erts-12.1.1] [source] [64-bit] [smp:8:8] [ds:8:8:10]
[async-threads:1] [jit] [dtrace] [sharing-preserving]

Eshell V12.1.1  (abort with ^G)
1> c(guardseq).
2> guardseq:add(1).
** exception error: no function clause matching guardseq:add(1) (guardseq.erl,
line 4)
3> guardseq:add(4).

For language support, best to use erlang-questions mailing list or libera.chat
irc etc.
