SL>Does the assembler command JUMP have anything in common with a GOTO?

Write your reply.

assistant: Both transfers control to another part of the program. And, that's
about it.
BTW, there is no JUMP command. Nor is JMP an assembler command. JMP
is a memonic that will cause the assembler to code for a machine
instruction. It's that machine instruction that "commands" the CPU to
jump to some other location in the program.
Machine code is as close to the heart of that beast as you can get.
It takes just one instruction to perform a JMP. A GOTO in
interpretive BASIC, on-the-other-hand, will likely take several
hundred to a thousand machine instructions to execute.
Compiled BASIC is a different matter.

Write your reply.

assistant: Hi Sylvain,
The "heap" is the memory that's outside of your program (or is it inside).
So, in a 64K com program for example, the heap is the memory outside of the
64K.
For the above, it would just be you conventional memory, taken from the
640K pool of free memory.

user: You are replying to Scott Little about "Jmp = Goto ?".

They wrote:
SL>Does the assembler command JUMP have anything in common with a GOTO?

Write your reply.

assistant: It would be the same thing as the GOTO, just it's the assembler version.
For example, let's look at a simple BASIC program: (classic old style :)
    10 PRINT "Hello,World!"
    20 GOTO 10
Now, in assembly this might look like:
string  db "Hello,World!"
10:
    push    offset string
    call    PRINT
20:
    jmp     10
The 10: section would print the string, much like the PRINT in line number
10 of the BASIC code. Then the 20: section just jumps to the 10: to repeat
the printing forever. This is identical the GOTO in line number 20 of the
BASIC code.
Cheers,
  Denis Boyles

Write your reply.

assistant: t??
You don't need the extra pusha, since the first one will save the
registers. Anyway I've found the "big" problem, change the second pusha
into a PUSH ES.
Again the pop/push are extras which aren't needed, remove those two lines
entirely.
Same thing again, but now change the first popa into a POP ES. Now try the
program, it should work now, or atleast no crash.
[ie:
    pusha
    push ES
    ...
    pop  ES
    popa]
Why? Well, I just doubled checked the PUSHA instruction and it ONLY saves
the following registers: AX,BX,CX,DX,SP,BP,SI,DI
You note that ES isn't among them. Since you modified it within the
handler, you must save this as a seperate PUSH ES call. The same thing goes
with popa, so you must use a seperate POP ES to restore ES.

assistant: In this particular case, the code you're looking at started with assembly
language output from my C compiler.  (The customer wanted some C subroutines
optimized, and the fastest and most accurate way to be absolutely sure I
started with correct code and logic was to use the C compiler's output .. as
occasionally braindead as it might be.)
I just assigned mnemonics .. ok, variable names .. for the otherwise somewhat
non-obvious stack values, local variables (also on the stack), etc.

always kind of off-the-cuff figured it was memory I could use with DS or ES

might be drawing on it also (e.g., alloc() and free() in C).
Hopefully someone else will come in here and explain it properly :-)

Write your reply.

assistant: Hum, an "incremental approach" .. one that sticks to the same methodology
that is used in demos where framerate is not taken into consideration ..
accept hooks the timer to do it .. bah..
 Why hook the timer if a) you don't need to, and b) it only gets in the way
f
(complicates) other hooks you might need for the timer? (music replay)
 Recalculating the position of an object based on time is nothing compared to
the time it takes to display that object.
 Also, you can be more versatile if you are recalculating the position every
frame based on a function .. because now it can be any function not just an
increment like the ISR solution.
 ..and exactly how many ISR's are you going to have set up for the different
things you will be doing in a demo that need incrementing?? Part 1 will need
one set of variables incremented in a set way, Part 2 will need a different
set incremented in a different way.. bah..
 ..the more I think about it, the more I think the ISR solution just plain
stinks =)

Write your reply.

assistant: Not precalculated. Recalculated. Why do you want to precalculate something
ou
only need to calculate once per frame?
As a simple example, the position of a vector ball could be expressed by:
  <nx,ny,nz> = <a * cos(time), b * sin(time), c * time>
..a simple X/Y spiral that travels along the Z axis
Least Significant Byte
Most Significant Byte
You do that..
Because if you do not, you cannot use DOS's recollection of the timer tick
(1/18.2 second) in conjunction with the value you read from the PIT.
When decrementing by 2, the PIT only triggers an INT 8 every -other- full
countdown (to retain the same frequency as when decrementing by 1) INT 8 as
you know is what DOS uses to keep its own tick count.
In essence, 32-bits of the current time:
  ((DOS_TICKS() + 1) << 16) - PIT()
..but only when the PIT is decrementing by 1.
(it defaults to decrementing by 2 and strobing its output lines in a
squarewave fassion)
Thats right.
And DOS's tick count increments 19 (18.2, actualy) times a second which is
based exactly on the PIT's countdown of one full word (1mHz / 65536)
