Hey folks..

I recently learned that the Doorway author was willing to part with his
source code, and after a few emails, I am now the new owner of Doorway and
all rights to it.

So here I am, going through the code.. I knew itd do some stuff that I had never seen before but didnt expect what I got :D

Simply put, the majority of the real functionality is done in either assembly or inline code.

The assembly: I believe I can find tutorials for that.

The inline code: I haven't found any tutorials about that..

Which leads me to ask: Does anyone know of a good tutorial about inline
coding?

Hello Michael,

Which leads me to ask: Does anyone know of a good tutorial about inline coding?

It is too specific for the compiler at hand to be described in a more general way. You should consult the manual of your compiler which will describe it exactly. It is not that different from assembly program, so the text will not be very complicated.

Success!

"Too specific to generalize" .. Okay, could see that. But I could also see where a list of opcodes and their corresponding assembly instructions would come in handy.

Not that much different from assembly.. If you know what youre doing.

Refer to the manual? It was lost many many years ago.

Michael,

I found a links that may or may not help in your search:

http://www.gnu-pascal.de/gpc/Assembler.html (this one has other links on the page)

http://www.msx.org/forumtopic|5310.html

I do have the TP7 manuals, but not here with me (still in Atlanta).

HTH,
Sean

Any textbook about the processor will do. But that's not the hard part - that's
more or less the same for all compilers.

What makes things complicated is to know how parameters are passed hence and forth; which registers contain which pointers, etc. Sometimes a few details are
described in the online help.

Refer to the manual? It was lost many many years ago.

I still have some Borland Pascal packages, complete with manuals. I might OCR a
few pages and send them to you if you use the same compiler.

You also might consider switching to a freeware compiler like FreePascal, available on the internet.

Hey folks..

I recently learned that the Doorway author was willing to part with
his source code, and after a few emails, I am now the new owner of
Doorway and all rights to it.

had never seen before but didnt expect what I got :D

Simply put, the majority of the real functionality is done in either assembly or inline code.

The assembly: I believe I can find tutorials for that.

The inline code: I haven't found any tutorials about that..

inline coding?

Hrmm...inline tends to be alot of asm in itself. In essence
its just direct machine code translations that can be translated
into ASM as well. Its a way TP or BP can interface with the
bottom level (ASM level) of coding. When I did a tutorial
teaching thing on IRC I typed up ASM stuff back ...gosh?...
a decade ago? Unsure where i put it. Would have ot look.
But i believe I spoke of inline then. I personally never
used it more than moving or modifying a small register
data set. You tried a basic websearch for tutorials?

Swag has 3 inline keyword searched files. Each have comments
on what they are doing. Might learn from them and see
a pattern of what is going on.

The old ASYNC routines also may have documentation on inline
stuff as well.

Course with doorway we must ask ourselves is it worth it?
I used doorway back in the day. But haven't in a decade.
I gotta wonder who still does. With windows systems telnet
is the way to go there plus some back doors. I gotta wonder
how hard you'll have doing doorway with windows. Might
be issues there never thought of. Good luck!

I recently saw some classes in delphi that does essentially
what doorway does the other day. In delphi doorway would
likely be a few lines of code. My how far have we gotten....

Yeah. Plus that was a 16 bit world. Asm was easy to handle.
In just 5 300k files of interrupts. Back then. Now its a
32 bit world and the asm files are megs bigger. :<

So the old inline code even if he knew it perfectly and 100%
had documentation for it then doesn't mean it'll be easy
now with the cpu changes since then.

Not a task I want for sure!

Hrm...lost manual..I came across a site...where was it...
hrm...can't recall...but it had all old borland manuals
and such in pdf format... planetsource.com?..no...not
there...hrm...dang...it was like 2 months ago. Can't
recall the name. Do a search for borland (inprise)
manuals and see what comes up. I think even some old
sites have tp5 for sale dirt cheap. I mean like 20$
I saw on one site. :)

There's always ebay :)

... I can feel my arteries hardening just being in the same room with it.
