Tomasz,
Well, this is good news !
Now, if we suppose AAPL is missing the last 5 quotations, then the
graph of
f=Foreign("AAPL","C",0);
Plot(f,"F",1,1);
is wrong.
We could have the correct graph NOW[before the 4.52 version],with
G=IIf(IsNull(Ref(f,-1)),Null,F);
Plot(G,"G",4,8);
But this correction is not enough for the CategoryGetSymbols()
example in the 4.50 users guide. The use of i in the last division
return Average / i;
is also wrong, i counts the names of the WL [the elements of the
comma separated string] and does not give the daily population of
the WL.
I hope it is clear now, the discussion was a bit boring for the
readers but, never mind.
The best solution for any user is to spend some time and fill the
holes of his/her database.
