Tomasz,
For us non-programmers, I get the sense of importance that VarSet and VarGet offer, but not in the practical sense.
For PT, is there a way to find out which positions are open, what there positionscores are, etc. using these functions.
I'm sure you have some very practical reasons for offering such functionality, but I'm not seeing it.
Thanks,
Gary
