As you say, there is no problem writing a system or an exploration for the
SAR. The problem that I have, and I think Neo also has, is that of being
able to build the SAR from scratch so that the code is accessible. This
would allow us to tinker with the rules in a way that is not possible with
the canned SAR. The fact that Equis have coded an SAR for the MS formula
language suggests that it can be done, but I rather suspect that the
programmers at Equis were not restricted to using MFL for their creation.
