 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.
