Because it has no meaning. Read the description of the FileSize()
function, and try to apply it to a Text file (composed of lines of text of
variable size).

Same answer. Read the docs, try to distinguish between C fseek() and TP
Seek() functions, and you'll have the answer.

I don't see the problems with Assign and Reset...

First, filelength() doesn't exist in C. Second, C only knows 2 types of
file: text and binary. Pascal let you declare files of any type, even
constructed ones. That difference should help you understand the
different approaches you have to take.

You're ridiculous. You're trying to compile C with a TP compiler. Does
your TP7 IDE limit you on the filesize or operations you can perform on
files you edit? No. And it's written in Pascal, and based on TV which is
written in Pascal. So what?

The printed documentation that came with TP7 is really good.

Please. Give up Pascal, stay with C. That'll be helpful to everybody here.

Easy, if you declare your file as a file of char, or untyped file. But
what will you do with the file size information? Pre-allocate things? Is
it useful at all? I don't think so.

easy.

Get the SWAG for snippets.

Yes, learn TP as a new language, not as a C descendant. Pascal is in fact
older than C.

Beware of hunters.
