Is it possible to call a procedure that has a parameter of type set in dwscript? I am exposing TDataSet and TADOQuery using ExposeClassToUnit.

var ScriptUnit : TdwsUnit;
ScriptUnit.ExposeClassToUnit(TDataSet, TComponent);
ScriptUnit.ExposeClassToUnit(TADOQuery, TDataSet);

The script that I cannot call is

if ADOQuery2.Locate('AccCode',  ADOQuery1.FieldByName('AccCode').AsString, []) then

I tried using 0 instead of []. This does compile but then gives me the message as below.

Runtime Error: VAR and OUT arguments must match parameter type exactly in Run

All help appreciated

Sets are currently not supported, you'll have to emulate them with boolean operations and write the event handler. – Eric Grange May 28 '13 at 09:29
Ok, thanks Eric. I'll let you know what I come up with. – Tom Robertson May 29 '13 at 01:56
Eric, I'm now supporting Delphi sets to script by creating arrays of an enumerated type. This works nicely using Delphi RTTI on the call from script to Delphi. – Tom Robertson Jun 19 '13 at 05:30
