Hi and thanks for your reply!

Since this is not a stored procedure in Iris database but in an MS SQL server, syntax does not work
"SELECT PackageName.ClassName_ProcedureName ('parameter')"

Normal call is Execute procedure name.

For example, when I call a procedure that does not use an output parameter, I use
"..Adapter.ExecuteQuery (.tResult, tQuery) Quit: $$$ ISERR (tStatus)"

However, because this procedure fills an output parameter, this call does not work. It then returns "Error! Function must return a value". So i suppose i need to use  ExecuteProcedure

Sincerely, Michael

Thanks for this. Exactly what i was looking for
