Write padded string to a file - how?

[Pallex]

Easy question, i`m sure, but its not obvious from the `Format` command help.

I have a simple string, which contains, 10 chars. But i want to write it to a file, padded out (with spaces) to 20 chars.

I`m after something like:

Line = Line & Format(!FieldFromDb, 20)

Any ideas?

Thanks,
Alex.
