SEL
Use the SEL command and ESD command to save only the errors from a test into the test results log file. Place the SEL command near the beginning of the test script and specify the name of the result file to use or create. The SEL command creates a new result file if one does not exist. If using an extension with the file name, the result file is saved with the specified extension. If a file extension is not specified, the result file is created using the default .ERR extension.
If another SEL command is in the test script, the system deletes the temporary file created using the first SEL command encountered in the test script. When the system encounters the “ESD DSK” command, it closes the temporary file created during the test (starting from the SEL command). It saves the file to the appropriate directory by either appending to an existing file with the same name/extension or creating a new file name/extension.
