The next window you should see has a text area containing the generated PL/I declaration. You can edit the contents of this area directly if needed.
For PL/I, java Dclgen saves the contents of the text area in a file in the ibmpliw\include using the table name as the filename with an extension of .CPY.
If you decide to save the generated declaration somewhere other than this directory, click on the Change Location and Save button. You can change the output directory and filename using the Save As... dialog.
You can change the table qualifier or editor name (including any extensions) by typing over the default information.
