OK, I guess it's just line noise, and I'll remove them. There's
another place where there's something that doesn't quite make sense to
me (yet) so I'll have a closer look there too (line 740 in TREK1).

I wondered about octal, but decimal 14 is Shift Out which makes more
sense. Sort of. See my reply to John K.

I'm sure that's it. The code has provision for various null inputs
too.

Oh, I have a few of those online, too :-)
