lol

this is only a file.....readed byte by byte (1026 bytes)... and then it reconstruct the file... this is that simple

this is the prog i use to make these .dba:

input "Source File Name=",Source$
open to read 1,Source$
open to write 2,"Rebuild.dba"

write string 2,"open to write 1,"FINAL.TXT""
write string 2,"Read Byte1"
write string 2,"while Byte1<>999"
write string 2,"  write byte 1,Byte1"
write string 2,"  read Byte1"
write string 2,"endwhile"
write string 2,"close file 1"
write string 2," "
write string 2," "
write string 2," "
write byte 2,asc("D")
write byte 2,asc("a")
write byte 2,asc("t")
write byte 2,asc("a")
write byte 2,asc(" ")

nb=0
for i=1 to file size(Source$)
   nb=nb+1

read byte 1,Byte
   FirstCar=int(Byte/100)
   SecondCar=int((Byte-(int(Byte/100)*100))/10)
   ThirdCar=int(Byte-(int((Byte-(int(Byte/100)*100))/10)*10))-(int(Byte/100)*100)
   FirstCar=asc(str$(FirstCar))
   SecondCar=asc(str$(SecondCar))
   ThirdCar=asc(str$(ThirdCar))
   if (firstCar<>48)
      Write Byte 2,FirstCar
      Write Byte 2,SecondCar
      Write Byte 2,ThirdCar
      if nb<>30 then Write Byte 2,asc(",")
   else
      if (firstCar=48) and (SecondCar<>48)
         Write Byte 2,SecondCar
         Write Byte 2,ThirdCar
         if nb<>30 then Write Byte 2,asc(",")
      else
         if (firstCar=48) and (SecondCar=48)
            Write Byte 2,ThirdCar
            if nb<>30 then Write Byte 2,asc(",")
         endif
      endif
   endif

if nb=30
      write byte 2,13
      write byte 2,10
      write byte 2,asc("D")
      write byte 2,asc("a")
      write byte 2,asc("t")

but this is not the point of my post

the .EXE in the .ZIP that i posted is a prog that i made in Assembly language... i know this is not a forum of assembly .....but..i was happy to finish my first prog...

here the code for masm:

Mattman, what is it you want to know about assembly using data statements? i am off mentally today...i am not sure what ur asking...even though the question is not directed at me i am hoping to help as i just learned about ASM...

do you mean..... ..what is assembly language is looking like?

if its your question... this is my code... it does the same thing than the ... DB prog..that i posted above:

this is assembly language:

I meant, how is it? to learn. Easy, hard, moderate with a quarter of a monkey's beard with a pinch of toenail clippings? How long did it take you to learn ASM?

hmmmm ..i dont know ... ..maybe one month to understand everything about ..pointer..memory .....register and everything else.. but i did not finish to learn thing about assembly (..im at chapter 9 on 25)

from .. the day that i did this program...i made many program.. more and more complex.... without reading nothing .. (only a interuption list) ... just playing around with pointer memory.. to be comfortable..with them.. and now im doing a Lander game.. in space.. .. almost completed (80%) .. ill post it soon..

but.... if you dont even know one programmation language.. i dont think you will understand asm ....easily...

i was already knowing... almost 10 programmation laguage... (web programmation included)... then i was already ... familiar with programmation... but ..try it.. you will see by yourself.. this is the better way to know....

ASM *shudders* get it away from me!
I had a bad time with z80, and I'm always going to have a bad time with all assembler. Why I even looked at this thread is mind boggling!

thx

it is so nice to read a commment like that

almost all of my code that is posted....have no reply...

or some poor comment... maybe DB user are not enough.. avanced to see the quality of my snippet...

now i am working on a 3d engine in delphi (witouth DirectX or OpenGl..i mean i do all calculation myself (the only graphic api that i use is 'SetPixel'))...

and im now modifying it to be completly ....with api.. i mean ill do EVETYHING.. myself.. i wont use 'uses'.. ill make my own window..

i will do it this way to code it in Assembly... but i do it in delphi first to ..be able to debug it easyly....

...anyway ill post it here even if its not related to DB.. for now here is an old version(exe or code):
http://www.brainwasher.free-host.com

late ill post my new version..

Yuck get out of the 16-bit world man! There's a whole new instruction set for the 32-bit architecture.

In fact, this only works for DOS. Try doing this as a Windows Executable, you'll find a nice surprise. It's a lot more complicated in Windows; therefore, you should use Direct X. That's the purpose of applications like this--is to remove that layer of complexity. This was wrapped around Direct X. Direct X is wrapped around assembly/C++/machine language--YUCK.

actually knowing ASM is an invaluable programming skill.
although Pascal/Fortran/C might offer you a higher level to a language, they don't always have what you require. Nor do they give you 100% access to your systems resources without having to rely on other people code.

ASM unlike the Higher level languages isn't limited to individal processor types or binary types or language setup structures.
Infact is it possible one of the most open-ended and powerful language there is. Allowing any user total access to no matter what system they are utilising.

As for making your own Graphics APi, very ambitious

but I do have faith that you can get something good working.
Be sure to checkout Quake and Quake2's source, they might be in C but they have particularly good Software Rendering engines. But no means fast by todays standards, but still fairly good to see how it was done a few years back.
MGL or MesaGL is another good opensource system ... what you want to do is focus on making the API with drivers to particular cards, and making the generics for them. nvidia and its community are oftenly nice to help out people with such things, ati you might hit a few brick walls but there is alot of info about thier cards.

(^_^) good luck mate
