Even if it could, this would be not enough, because sqrt(2)

This option is not in the Standalone Settings because the engine does not
yet support suspend/resume explicitly. IIRC, in the past we had discussed
what needs to be done to properly support suspend/resume messages on

Suggestion for RM to try: Don't fuss about non-integer points—do all the

I’m sure any system would not attempt to parse an infinite number of decimal
places. The turtle would probably be placed at 1.41421356237 pixels. If you
want to try more accurately than that, here’s the first million decimal places:

Do you mean for reading them or printing them?
squirt is for printing qr codes
mergzxing lets you scan them, HOWEVER, I would strongly recommend that you
use mergAV to scan them as it is more up-to-date, and has better options.

Yeah, I think this is due to that change a while back (the partial pixel

Thanks for the responses. I am actually interested in *bar code* reading rather
than QR codes.
Do any of these solutions do bar codes? I’ll have a look as well in the
meantime.

See my email. mergAV is choice #1 for reading. mergZX reads, but is not
as advanced as mergAV and really should be deprecated because it does not
have any features that mergAV does not have. It just uses a different code
base.

When a question about what's available for "mobile" is raised, I always
read it as "android, iOS, and maybe even Windows-mobile". I never

Roger, I agree. I was not aware, until you mentioned it, this evening,
that zx ran on android. If that is the case, and mergAV does not, then of
course it should not be deprecated, at least on Android. On iOS, it is not
as useful for barcode scanning and recognition as mergAV is. Anyway,
