  1. Use the file component to read in the text file contents
  2. Use the dictionary blocks to work with the data
  3. Ensure the contents of the text file is a dictionary (use Web component blocks to decode if required)

You could upload the text file from your PC to the Media Folder in the Designer, then load //filename.txt at run time using the File component.

No, you have to read the file earlier, in Screen1.Initialize

The GotText event runs way longer after that, in micro time.

Also, you have to copy the text into a global variable where you can get to work parsing it and tracing the inputs using the Companion's Do It facility.
