Removed comment about entering the file name in the shell. This is irrelevant. Accepting the byte count correction.

Using the program name to store data without counting those bytes

Example - this bash script prints Hello World!

echo $0

Must be saved in a file called Hello World! (entered on the shell command line as 'Hello World!' or Hello\ World!).

When using the filename to store data, add them as extra bytes to your solution similarly to any non-standard parameter.

For example the correct byte count for the above is 7 (echo $0) + 12 (Hello World!) = 19 bytes.

If the file name contains the backslash, it will get printed. How to enter the filename for the shell is not the same as the filename itself. See comment

Filename as data is fine, the only problem is not counting it. (The comment describing this has 2x the upvotes of this answer). Also properly golf the filename: word-splitting is fine because echo prints args space-separated. Still probably need to escape the ! for history expansion.
