Re: Strip a ™ character

[JB]

Well then Dr. Hawkins won’t need to take things
too seriously if he is offended.  He is a big boy
just like me and you.

As for my business it is nice you are concerned
about the damage but there was a lot more than
that at a lot more levels.  I can assure you these
people are everywhere and they are organized.
It appears they have some form of tapping system
and they use gossip or other means to attack too.

But the subject is the code.

I do not know unix and you may be right.  The thing
with the extra chars is critical.  The code to convert
is simple.  As for the code being converted it was all
from a field.  Write something in the field on one line
then use the code to convert that line to binary and it
works.  You put that code into the field and all it knows
is you have put 6 characters for each letter you had in
the field and those characters are now a combination
of 0’s and 1’s.  So you now have the same type of text
in the field.  To convert that to Hex you take 8 chars out
of the field and then replace them with 2 chars that can
be a number and a letter from A to F.  The letters can be
either upper or lower case but it will be used the same
way in the conversion.  Most people are not actually doing
the conversion from the binary 8 char to Hex 2 char they
call a routine from a library similar to me call a function you
wrote.  So the conversion if successful at all should always
be successful and will not give you extra chars.  The text
returned is what will always be returned so if your function
takes text from a field and returns it then there is really no
big change unless you change its form.  What is being done
to the text is not changing its form unless the code used is
somehow changing it but if that is the case you would not be
able to have a single char or line work either.

There is no reason to add more chars just because you have
used the conversion on text from a different line.  If it was doing
it on text from the first line too then that might be possible but
just telling 8 chars they are now 2 chars does not add AA and
the form of text entered or returned does has no reason to be
changed just because you entered text from another line.  I did
it where I only used the eight chars on each line.  I can choose
any one line from the field and it works fine.

I have ways that I think I can solve the problems and if that does
not work I can use GCD.  The problem needs fixed or you will be
left with a problem and in that case why not just remove the code
that allows you to convert Binary to Hex?

Leaving bad code is like selling milk and then the user opens the
container and finds it does not have any milk.  If you know milk is
not being put into the containers then do not sell the milk or fix it.
