| | Hello. I've started to learn assembly this week, and I found a example that I couldn't understand, so, if anyone could explain it to me, I would appreciate. [CODE]int increment(int x) { x = x + 1; return(x); } [/CODE] and this got translated to: [CODE]pushl %ebp movl %esp, %ebp …  |
| | I was wondering why the line: [CODE]sub dx,offset a1[di+1][/CODE] Actually goes on and does [CODE]sub dx,a1[di+1][/CODE] If di=2 then it would b: [CODE]sub dx,a1[3][/CODE] I dun get why it ignores the offset...why doesn;t it take the adress or atleast the index ... (Not sure if it should get the adress … |

| | Hi, I'm trying to write a maze program in MIPS and have almost all of it working except the recursion part. For some reason, it does not correctly move through the maze. In my code, the maze is fixed at 5x5. A 1 in the "maze" data indicates it's blocked. … |
 | I am interested in learning simple 16 bit interaction of code between Turbo C++ 3 and Masm 6.11. Could anyone describe how that would basically work in terms of what statements in either contribute towards the interaction. Thanks. |
| | Just some random thoughts :) DOS runs natively in 16-bit Real Mode. EMS, and Himem, memory managers (to my best knowledge) provide their services by jumping in and out of Protected Mode. 32-Bit Protected Mode programs use a DOS extender to jump into Protected Mode, and provide 32-Bit services. A … |
| | Hi all I need an assembly program (x86) that gets x and n from user then calculate x^n (x power n ) and shows the result. Where can I find an opensource program for it? Thanks |

| | I wanted to get a feel for preemptive multi-tasking. The easiest way I could think of was to write Real Mode boot code. To compile: [ICODE]nasm bt.asm -o bt.img[/ICODE] I ran this by loading bt.img as a floppy image under VirtualBox. Not sure if it'd work with other emulators. The … |
| | The assembly code below is equivalent to: [CODE]a=1; b=1; if(a=b){ x=2+2 }[/CODE] It is generated code so don't worry about inefficiency. My problem is when I use the sete command I get the error "error: invalid combination of opcode and operands". Here is the code: [CODE][list -] %include 'win32n.inc' [list … |
