The logic and instructions used in programming the application must
be:
• easy to understand.
• easy to trace.

All logic should be reviewed and tested. Keep safety-related logic and
standard logic separate.

• Name
• Date

• Any other user identification
Test the Application Program
This step consists of any combination of Run and Program mode,
online or offline edits, upload and download, and informal testing that
is required to get an application running properly.
