assistant: Hi Sylvain,

That's possible since they are all part of DOS though I'm not sure exactly.
           INT 21  DOS Function Dispatcher
           INT 25  Absolute disk read
           INT 26  Absolute disk write
           INT 28  DOS idle loop/scheduler (undocumented)
I would imagine that these four atleast would set the flag since they are
pretty important ones. For example, you wouldn't want to call DOS when it
was already access the disk. I remember though that certain int 21h
functions are safe, but others are not. Something like the lower numbered
functions are ok, but the highter ones aren't.
One would need to read up on the INDOS flag and how it applies to writing
TSRs.
Probably since INDOS=1 would mean that DOS was "active" so you should be
careful. Perhaps making the DOS call within DOS screwed up some file
buffer data or something.
Cheers,

with NOP's anylonger..

assistant: Hi Moderator,
I agree that it should be mentioned in the rules simply because in most echos
it *is* prohibited. Unless we know otherwise most of us tend to expect
encoding to be a no-no in any echo we read. I believe anything which is
contrary to what is considered the norm should be specifically stated.
It would be well worth making that combination the "official" means of
posting lengthy code in the echo. A mention to that effect should be in the
rules. BTW, when are the rules due to be posted again? ;-)
There is no actual Fidonet restriction on the size of Echomail messages,
although a fair amount of software (including the reader I'm using) will
still choke on anything over 32Kb. As 32Kb is also the limit in Netmail it
should probably be adhered to in the echos as well. While I wouldn't want to
start receiving too many 32Kb messages I would also not want to use any
software which couldn't handle it. Under the circumstances, I think a 200
line message should present no problems.

assistant: Hey Sylvain!
I've never used dv, but it seems like it handles things differently. The
program worked ok though with my DOS/WIN setup. Looking at a reference it
says that IRQ-0 (8) is intercepted by dv. Perhaps that's why the program
crashed.
Yes, the command prompt looks like it goes through various DOS interrupts.
You'll notice the "blue" border on disk i/o and when other functions are
called, like keyboard input.
Yes it does, but you probably only need it when using the DOS interrupts.
Hopefully you would be safe using a BIOS call or other interrupt for
things.

user: You are replying to All about "Accessing memory on heap".

Write your reply.

assistant: First of all, I am very new to assembly programming, and don't have a book to
learn from.  I'm using the Watcom compiler with inline assmbly to start (it's
sure a lot easier than the 20+ lines needed in a bare bones assembly program
which only returns to the OS).
In all honesty, I probably won't ever go to writing programs entirely in
assembly simply because C is so much easier.  I would however like to write
time sensitive portions of code in assembly.
I have managed to write simple portions of code which takes 2 arguments, and
returns one as the sum or the difference of the two, and simple stuff like
that.
What I'd like to do is pass a pointer variable to ASM, modify the data on the
heap while in ASM, and return nothing having done my task.  (I know how to
return nothing).
Another thing which I'm curious about is variables in Assembly.  I don't know
how to define variables, so I've been passing variables and using them, or
using the registers.  Also with regards to the registers, can you put
floating point values in them, or just integers?
Thanks in advance for answers to any of the questions.
