I knew it had to be simple. I neglected to change to the directory where the script file was located. See the ChDir command in the Delphi code below. Problem solved unless someone has a better way. Thanks.

procedure TForm1.Button1Click(Sender: TObject);
begin
ChDir('C:\ABSFIREBIRD\SQLTEST');
WinExec('isql -i MyScript.sql',SW_SHOWNORMAL);
end;

Because the script didn't work as expected when launched by Delphi or Wise, I created a batch file that also works fine from command line or when double clicked. However, when I launch the batch file (or isql) from Delphi or Wise, the command window just flashes and the script does not run.
