TEXT = sprintf('%256s', 'Unformatted Data Version=');
fprintf(FILEID, "%s\n", TEXT)

Hi @Jaden Hoechstetter
In MATLAB, you can convert a string to a fixed length by padding it with spaces or truncating it to ensure it is exactly 256 characters long by using the "pad" function.
text = 'Unformatted Data Version=';
textUpdated = pad(text, 256);
disp(textUpdated);
Unformatted Data Version=
Here is the documentation link for "pad" function:

I hope it helps your query!
