You don't. This is to format output, so you already know
what you're putting in, and don't need to re-read it.
I'm writing a gif encoder, forkosh.com/gifsave89.html
For a decoder, you would be reading those blocks,
and then your problem is indeed a problem. I'd have
to write the corresponding scan-like function to smemf()
to deal with that.
