Nat, you can create your output file in any directory, not just in C:\ root. In order to do that, just modify the filename statement.
As for the map not displayed, please try the following statement at the beginning of your code: options lrecl=max;
Also note that your code must be placed on a web server in order to get the full functionality, such as YouTube video.
"Check to Confirm" is working exactly as intended: you have to check it.
