assistant: Hi Jerry!
       I don't usually worry about defining the type of file in a header
(like ORH 100h), because I use A86 and you tell it what type of file you want
through the command-line.  .COM or .OBJ.  If I tried to compile that program
to a .COM with A86 no matter what type of ".model" was at the top, it
wouldn't work :).

       It seems that which functions you actually use would be dependent for
which device your drove.  For example, if I was making some type of ANSI.SYS
driver, wouldn't I need to intercept the Interrupt (DOS Interrupt?) that
prints to the screen?
       Yes, in fact I just got a "flood" (10?) of them about 2 days ago.

I use a DOS shell that modifies the "master" environment whenever I set

environment variables that I set in the "master" environment.  Neither
causes any problems, either in native DOS 5.0, or OS/2 2.1's "DOS box."

NC> What's a NOP?

Write your reply.

assistant: Hey Nick,
  NOP means "No-Operation".  It's an instruction that does nothing but
  take up a clock cycle.  About the only use for them is to provide a
  delay after doing a memory access or I/O.  Occasionally you might have
  a device on the bus that responds too slowly and you might insert a
  couple of NOP instructions to give the device time to "settle".
  Back when I was at Quadram, I would use the NOP when testing some of
  our boards when writing values to the registers.  Before reading the
  value back after writing it I sometimes had to insert a couple of NOP
  instructions to give the value time to be latched to the input side of
  the register.

assistant: Hey Mike,
  Programming at the device level can be a lot of fun, but takes a great
  deal of work.  I spent the first five years or so of my PC programming
  doing device level work, writing device drivers and system utilities
  (RAMdisks, spoolers, memory-management drivers ... stuff like that).
  As far as what's available currently, I'd check your local university
  if there's one near by and see if they offer courses on the subject.
  I'd also simply get a machine, an assembler and compiler and simply
  roll up my sleeves and start experimenting.  There are a lot of books
  available on the subject of programming at that level, but you might
  not find them in the local bookstore.  (Everything is going "Windows"
  these days).  I'd suggest that you check out some of the larger
  bookstores and even check into the BookClubs.  I obtained literally
  dozens of books through book clubs.  Pick up a copy of BYTE and you'll
  probably find a card or ad for one of those clubs.

user: You are replying to Nick Coons about "32 bit code within 16 bi".

Write your reply.

assistant: Hi Nick!
SHR for my multiplication and division.  Here's what I have to multiply by
640 (AX contains the Y position)
       temp    dd ?
       .
       .
       db 66h
       shl     ax, 9
       db 66h
       mov     [temp], ax
       db 66h
       shr     ax, 2
       db 66h
       add     ax, [temp]
       temp    dd ?
       The DB 66h's are suppose to make those 32-bit because I am actually
wanting to use EAX (which is the same size as the double-word TEMP).  The
problem I am having is that A86 doesn't recognize this, so it doesn't like me
trying to move a double-word into AX.  Any ideas?
The best idea would be to find A86's bigger brother A386 which allows you to
code 32 bit assembler. It's by the same author and you'll probably find it
where you found A86. Failing that, I've come up with one idea that seems to
work with MASM.
Here's the idea, break up your dword temp variable, into two seperate word
variables. This way you'll be moving a word value into AX, but the DB
override will put a dword into EAX.
temp LABEL dword            ;this LABEL makes TEMP refer to the whole dword
    lTemp   dw ?            ;which is made up of the low word and
    hTemp   dw ?            ;it's high word
       .
       .
       db 66h
       shl     ax, 9
       db 66h
       mov     [lTemp], ax
       db 66h
       shr     ax, 2
       db 66h
       add     ax, [lTemp]
Most likely you won't need the dword label line, just the two high/low words
of the dword. Since EAX is a 32 bit register, it will hopefully load the
whole dword for you.
Hope that helps.
Cheers,
  Denis Boyles

Sorry, Nick, but I think dx:ax looks like a 32-bit register-pair. It isn't
like a simple register, but it definitely holds a 32-bit value as you pointed
out yourself earlier in this thread...
The line `mov dx:ax, [temp]' would therefor have to move a 32-bit value,
which a 16-bit machine isn't capable of.

Allow you to rotate signed numbers, without losing the sign-bit.
ROLL? I don't recall mentioning anything to do with ROLL?? Perhaps you mean
ROL? If you are trying to say that ROL and arithmetic shift are contrary,
well yes they are.. THAT was my entire point. Lack of arithmetic shifts my
whole point. It would be nice to have RAL (and RAR) so that you can perform
all the code optimizations that SHL and SHR provide for unsigned numbers on
signed numbers too, without extra code to manage the sign-bit.

assistant: Are you programming in assembly under Win95 and WFW, David? I'd be
interested to hear what you are using for source references.
Batch file? And the Dos Copy command? Hm.
Okay... well, checking the file's status from a batch file is
inequitable in my considered opinion. Between the time you check the
file's status and the time you start to copy, someone may try to access
the file. I would recommend that the safest course of action would be
for you to write a program that does all the checking and copying for
you. This would give you the most security and prevent any accidents.
First, open and lock the source file. Then attempt to open the target
file using Dos function 6Ch -- this allows you to easily disable Dos
Int24h error handling so that Dos will return the sharing violation
error code to the program instead of prompting the user for interaction.
If, or when, the coast is clear your program copies the file, then
writes 0 bytes to truncate it (if necessary), then close the file.
Does this seem viable? I can be more specific if you like. Actually, it
would probably be a pretty short program to write.
Take care.
