Bill,
An indirect method would solve the situation.
Have a look at
p1=Param("p1",10,10,200,10);
p2=Param("p2",100,100,200,10);
P=IIf(LastValue(StochD())>50,p1,p2);
y=MA(C,p);Plot(y,"MA"+WriteVal(P,1.0),1,1);
It will automatically select 10 or 100 according to the IIf criterion.

a constant because the values are cached and not re-read during

(COND, x, y) to define the default value where, for example, COND
could be Interval(), etc. Has anyone found a work around to this
limitation in Param() or have a suggestion as to how to proceed?
