And using symbols insteadof real sticks was much better.Decimal SystemMost people today use decimal representation to count. So, the number 5 was firstrepresented as: | | | | | (for five sticks).5Later on, the Romans began using different symbols for multiple numbers ofsticks: | | | still meant three sticks, but a V now meant five sticks,and an X was used to represent ten of them!Using sticks to count was a great idea for its time.

Long ago,humans used sticks to count, and later learned how to draw pictures of sticksin the ground and eventually on paper. part 12: controlling external devices (robot, stepper-motor.)Numbering systems tutorialWhat is it?There are many ways to represent the same numeric value.part 11: making your own operating system.part 6: arithmetic and logic instructions.part 5: library of common functions - emu8086.inc.Because of this, it's even possible for programs to re-write theirown instructions, then execute the instructions they've changed.4ŎMU8086 Tutorials8086 assembler tutorials

Unlike the previous example which carries outeach step by itself, this one is much smaller because it uses a built-ininterrupt function of the operating system to write to the display.The integrated 8086 assembler can generate console programs that can beexecuted on any computer that runs x86 machine code (Intel/AMD architecture)The architecture of the 8086 Intel microprocessor is called "Von Neumannarchitecture" after the mathematician who conceived of the design.NOTE: A CPU can interpret the contents of memory as either instructions or data there's no difference in the individual bytes of memory, only the way in whichthey're arranged. If you click examples and browsec:\emu8086\examples, you'll find HelloWorld.asm which assembles intoonly a 30-byte executable. There are many ways to print "Hello,World" in assembly language, and thiscertainly isn't the shortest way. You can also click step back (or press F6) to see what happenswhen reversing those changes.4. You can then click single step (or press F8) to step through the code oneinstruction at a time, observing changes in registers and the emulatorscreen. If the assembler succeeds in creating the file, theemulator will also automatically load it into memory.3. Theprogram then attmepts to assemble and save the executable toc:\emu8086\MyBuild. To run this example in the emulator, click emulate (or press F5). All other codeis straight-forward and writes directly to video memory.2. Thecompiled executable is only about 100 bytes long, because it uses nointerrupts and has only one loop for color highlighting the text. All comments are green and they take up about90% of all text, so don't be scared by this tiny "Hello Word" code. A code example with manycomments should open. Click code examples and select Hello, world.
