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

IB_Query1.ParamValues['xxx'].AsString := '';
And I *think* you can (and maybe need to) omit the casting method, provided
the input data can be resolved to the correct type, since ParamValues is a
Variant type. Can't verify it myself just at the moment, though.
