Hello SirStorm25
Didn't expect to see you here. Check the top of system unit and systemh.inc

Sometimes we forgot whether a function argument is passed by reference or by
value. What if the result is actually important? For instance, consider the
following (WARNING: True story):
function Align(Addr: Pointer; Alignment: PtrUInt): Pointer;
then we forgot that Addr is passed by value, so in

I don't think so. The compiler understand that a procedure doesn't return a
value while a function does (i.e. trying to return a value from a procedure
causes compile error). I haven't checked how compiler formats

Well, for the iso... I guess it's possible to read files stored in it. Grub
can read menu.cfg, so why can't we? The problem is... how?

What revision do you want to be merged. I thought r11434, but that has made it all
the way into fpc 2.2.2, as far as I can see:

Yes, that was it =)
Excellent. I assumed it wasn't merged because no answer was given to my e-mail.
This is pretty good for that part of the book =)

Hi All!!!
Im trying to develop reading capabilities for an OS im helping to develop.
When enabling the FPC_HAS_FEATURE_TEXTIO from the RTL, I get a few errors
involving
the file: Text.inc.
All of the errors returned are mainly "do_" functions.
E.g:
do_read
do_write
do_close
do_erase

Depends. If you mean in an executable format, then it is usually already
relocated code, to be loaded on some OS dependant address.
Some variants also have hints for load address and/or

Hi!

No. Because there is no such ".bin format".
File name extensions (e.g. ".bin") are NOT the file format[1] (e.g. JPEG
image)!
Unfortunately Windows strives to let people assume that, but it is
wrong. The extension is an ar

The finaly question is: where do I put these?
do I create my own sysfile.inc with just these functions, or do they rely on
other functions located within the same file?

Of course, usually it's without the "not"... ;) And with Boolean functions it's

Well that is not that hard:

do_write - write bytes to file
do_close - close file
