This account contains PIN, the Procedure Interpreter designed by
James G Downward as a much smaller version of AT. I have rewritten
most of it to use file primitives (instead of FCS) and to do its own
parsing (instead of using CSI) - this has made it vastly smaller. I
have also added a 'Chain' facility.
