Where to see the output of my Application Engine Program ?

Question

Folks,
Hello. I am creating my first AE program in Application Designer and test it in the 2-tier mode. I open the AE program in Appication Designer and click Edit ->Run Program. Then open the log file to see its execution and know the AE program is running out. But I don't know where to see the output of the AE program.
The AE program is only executing a SQL "select" statement. Its output is the ResultSet of the SQL.
Do any folks know where to see the output of the AE program ?
Thanks in advanced.

The AE program is only executing a SQL "select" statement. Its output is the ResultSet of the SQL.
Do any folks know where to see the output of the AE program ?The output of the select didn't go anywhere. You have to actually do something with the values selected. App Engine selects them and puts them in memory (if you tell it to through %Select), but where those values go depends on you. If you have a DoSelect, then your next action may be an SQL insert/update/delete or even another %Select. If it is another %Select, then I would expect your next action to be Call Section or PeopleCode.
If you just want to select data and print it to the app engine log file, then I would setup a step with a DoSelect/%Select and then a PeopleCode action. In your PeopleCode action, use MessageBox(0, "", 0, 0, "The value in field MYFIELD is " MYREC_AET.MYFIELD);
