The difference will have to do with the fact that Dialect 3 doesn't do
implicit casting of integer to string and vice versa. Is your gsEmpID
variable an integer? If so, cast it as string before you use it as an
input to your proc,


ParamByName('EMPLOYEE').AsString := IntToString(gsEmpID);

Also, take out the SUSPEND statement. It doesn't belong here.
