> Oops, sorry, Fields['xxx'] is implemented for the Fields[] array.
> For parameters the property is ParamValues, not Params:

same error here:

IB_Query1.Fields['xx'].AsString := '';
IBOQuery1.Fields['xx'].AsString := '';

[Error] Unit1.pas(29): Incompatible types: 'Word' and 'String'
[Error] Unit1.pas(30): Incompatible types: 'Integer' and 'String'

like I said it must be something wrong with my ibo instalation or
version (4.3.Aa).
