This error is because, in ECLiPSe, you can't just type


since `.' is a special character.  You need to make the file name a string
"arrow0.txt" or atom 'arrow0.txt'.

>From what I understand of Josh's reply, you want to construct the term

	@(compile("arrow0.txt"), d)

and send that.  I guess constructing the term would look something like this
(big disclaimer: I don't really know Java, and I've never used the
Java-ECLiPSe interface or this RPC stuff...):

	new CompoundTermImpl("@",
		new CompoundTermImpl("compile", "arrow0.txt"),
		new Atom("d"))
