My guess is that you are exceeding the character limit for the line of the Driver Station and it's getting truncated. That display does not line wrap, it truncates extra characters.

If you open Execute File, there are several VI's which do the actual processing of a file into arrays of lines and later arrays of arguments. I believe the first one is read_auto_file and the second is part of ExecuteCommand.

It's never explicitly defined how many arguments to expect. The interpreter passes all arguments to the command and lets each command deal with it - Some do, some don't.

For the actual breaking up into lines, it first breaks them up by newline into an array of lines, then FOR's through each item. If it's not a comment or blank line, it executes the command on that line. That VI breaks up the line into an array of strings separated by spaces. The first one is the command name, the rest are arguments. It finds the command with a matching name to the command called, and calls it with an array of arguments.
