### Starting and Running AP2

When running AP2 for the first time, it is necessary to set the Data Path. The Data Path points to the directory where all the data files for AP2 are located. Every AP2 script that requires a data file uses an environment variable AP2PATH, which is set by AP2.

The Start Test button tests the selected scripts. To test scripts, highlight the selected scripts and click on the Start Test button. After each script is completed, the status for that script is displayed. The output for every script is located in the OUT directory. The output file has the same name as the script with the extension of "OUT".

The View Output button allows the viewing of the files that are generated from the execution of the *.P2S files. To view the output for a specific script, highlight the script, and click on the View Output button.

The Data Path button displays a dialog box and allows you to select the location of the AP2 data directory. AP2 will not run correctly if the data path is not set to the directory containing the AP2 data files.
