But using .WriteAnsiString() doesn't create a plain text file, so the
result is useless. And as my last post says, the method Gerard
suggested is also not 100%.
It seems extra hard to create a normal, plain, standard text f

output text file. The one unit I fixed by using

That's kind-of why I wanted to use TFileStream. I use it for reading
binary data, and thought to us
Hi,
I'm reading in a WORD (2 bytes) from a binary file. I can display the
Hex format of that value without a problem, but I would also like to
display the String value of that WORD variable. It's the first 2 bytes
of a file, which contains the "magic number" of the file.
I would like my program t

That should never be a problem for my tool though. The tool I am
writing is specific to the INF help format. The tool dumps the file
structure to a text file. (I need this for debu
