Also, lacking an @UPDATE event, or a "GOTO TOP" elsewhere in the code, the 
only way to get to line 1 would be to press SAVE on a screen somewhere. (Or, 
in this particular example, execute the PUSHKEY "[SAVE]" on line 5.)

While you are correct that this is "false", your explanation is partially wrong.
