It's coming up with a 'FieldName myboolfield not found' exception
when I use the

> if (IB_Query1.BufferFieldByName('myboolfield').AsBoolean='Y') then

line
and a general AV when I use

> if (IB_Query1.BufferFields[4].AsString='Y') then

Now this did not happen when I first created the code, it is only happening
now after adding more queries and DrawCell calls.

The field definitely exists, and when i step thru the debugger, slowly,
these errors do not show up. It appears as if there is a buffer not being
ready to query like this. There must be another more reliable way to get at
the values.

This is Delphi stuff isn't it - AsBoolean will return
true/false not a character?
So
if (BufferFieldByName('myboolfield').AsBoolean) then

Historic compatibility ( I think <g> )
