Just thought I'd try to clear up confusion on what Mince & The FinalWord
are looking for in a file:
1) "Read Error or No EOF" almost never means that Mince&TFW truly got a
read error. It is always just complaining that there was no ^Z at the
end of the file. If you just type a command, the screen will be updated
and your text should be intact. The IBM version of TFW has also shown a
propensity for stopping input at ^@'s too... I believe that the editor
can read them just fine, but some part of string input in formatter
treats these NUL's as "end of a C string" and thus end of file.
2) Why are you seeing ^M's? Well, Mince&TFW expect ^M^J combinations in
the file. If there are just ^M's, Mince&TFW won't see that as a new
line. Also, a ~^J (a linefeed with its top bit on) is used to signify
a new line in Mince&TFW, so if they read that character, you get a new
line there. The easiest way around this is to do a global replace of ^M
with <NL>.
3) If you're using TFW, don't bother turning off top bits using your own
program or "PIP [Z]" -- just use the little-known (and mis-named)
"Capitalization Menu" to clear highlighting on the entire buffer.
4) ^@'s are the worst. Mince&TFW can't replace them or search for them
or anything. All you can do is examine for them by hand or write a
utility program to strip them away. We ran into a lot of these when
converting Easywriter files for TFW.
Hope this is more helpful than obfuscatory,
Brian
