ANONYMOUS wrote: I believe Chris said either in the forum or the project sheet that all statements must start at the lefthand most side of the file unless it is a statement in a function. Not sure where a comment could appear (because technically comments aren't "part" of the function definition). You could just check if the first character is either a tab or a comment (if a comment just ignore the line), otherwise if a tab process as normal (if you see a comment then ignore the rest of the statement).
