Question: How do I store Maple input in readable format

Some years ago a postdoc working with me insisted to use Maple, since he was used to it. He left me some *.mws files with some calculations we had published together. I'd like to re-use the code now, preferably transposed to C or another programming language (there is not much use of Computer algebra in the code). Unfortunately it appears not so easy. I found the free Maple reader, and at least can now see the code. However, I did not find a way to copy-paste code from the Maple reader to a text file, or any other way to store the code in readable format (avoiding the Maple reader). I try to store the code by printing from the Maple reader with a kind of pdf writer, and a process started which kept my Laptop busy for more than an hour now without any output.

At the moment it looks like the two years of Postdoc work is lost, thanks to Maple and its strange restriction policy.

Can somebody let me know how to save the Maple input code of a *.mws file in a text file?
