Over two hundred functions and variables are accessible through an ARexx
port. The ARexx interface was implemented without using any routines from
the ARexx library (which is suggested by Bill Hawes). This means that ARexx
does not have to be present in order to use CEDPro's ARexx interface. That
is, a program written in C or any other programming language can directly
interface to CEDPro using the methods defined by ARexx, even if ARexx isn't
around.
