[amibroker] Barcount vs BarIndex

["Barry Scarborough" <razzbarry@xxxxxxxxxxxx>]

I understand that barCount is a var with the number of elements in an 
array and BarIndex is the offset to a cell and BarCount = BarIndex() + 
1. What I don't understand is when I use printf to show the bar number 
the value is wrong. This is what I use to show the value of each

printf("Barcount " + NumToStr(BarCount, 1.0, False) + "\nIndex " + 
NumToStr(LastValue(BarIndex()), 1.0, False));

If I use the Yellow - to put all bars on a sheet then BC = BI + 1. In 
this case BI = 8652 and BI 8651. 

Here is the interesting part. If I use the Green + to show the minimum 
number of bars on a sheet, 11 in this case, and I put the cursor in the 
white space to the right of the last bar or on the last bar then BI 
stays the same but now BC = 44. As I move the cursor left to each 
preceding bar the BC gets larger, +1, for each step to the left. The 
left most bar 54. If I press the yellow - to show more bars then the 
right most bar has a value of 51 now, not 44. And the BC number 
increases +1 from 51 as I move the cursor left to each bar. 

What is going on? At least I would expect BC to be 8652 on the right 
most bar and decrease 1 as I move the cursor the each bar to the left. 
BI Stays the same no matter where the cursor is.

Thanks,
Barry
