ASCII TO HEX TO ASCII
Using a 2dim array is not worth it. Strings ARE in ASCII, so if you have the ascii code as an integer somewhere, you just print it directly to screen, which outputs it as an ascii character. For instance, if al=65, you output an 'A.' Your problem is much easier if you were to go directly to... -
Help with a database program
...repititive code, chances are you're doing it inefficiently. Also, I suggest you sort INDEXES and not the actual records, moving records around can be *** time-consuming. "Information has a tendency to be free. Which means someone will always tell you something you don't want to know." -
Help in a design of compressor program
It would be nice to know WHERE it doesn't work, too... Does it assemble okay? Does it link okay? Does it load and run okay? Does it load, print a lot of computer-understandable curse words, then go beeping until you press the reset button? Does it toast your computer? "Information has a... -
String Input
There is no string input function in BIOS. If you want an input function more flexible than DOS's, you want to build your own. If you're using Windows... hey, you probably aren't. "Information has a tendency to be free. Which means someone will always tell you something you don't want to... -
Screen Refresh/ Display
The flicker is probably caused by not using direct video access. If you're doing BIOS access (omg!) it'll be ridiculously slow even on later processors. Also, drawing pixel by pixel is not recommended for any 16-color video mode, especially for horizontal lines since you can draw up to 8... -
Using Linked Lists in ASM...
You might also try to *SEARCH* on win32asmboard.cjb.net . Some of the people there have had to face problems of interfacing C++ to ASM, and they may have posted some things you can use. The point though is to use the *SEARCH* function on win32asmboard.cjb.net since if you ask, you stand a... -
Using Linked Lists in ASM...
...are using MSVC++, you may wish to find documentation on COM for ASM programmers; since COM is mostly based on MS's C++'s class structure, you may *glean* some information there. It seems safe to indicate that any class is equivalent to a struct: struct node { void (*vf_table); /*virtual... -
Incrementing a 64-bit memory location in assembly
No. "Information has a tendency to be free. Which means someone will always tell you something you don't want to know." -
Incrementing a 64-bit memory location in assembly

16-bit mode and 32-bit mode
Yes, if the OS supports it. As it happens I saw some OLD Windows code once which allowed a 16-bit real mode DOS program to send information to a 16-bit protected mode Windows program, through the clipboard... "Information has a tendency to be free. Which means someone will always tell you... -
Largest Number
It's easier if you convert the hex string into a binary number first. "Information has a tendency to be free. Which means someone will always tell you something you don't want to know." -
New to Assembly
Do some research on binary to string conversions, this forum has a 'search' feature ;-). "Information has a tendency to be free. Which means someone will always tell you something you don't want to know." -
N! up to 71 digits
No, multi-word maths will still work. The only problem is that you have a LOT of work to do to implement it. In fact, using unpacked BCD (which is what you suggested, storing a single digit in one byte is unpacked BCD...) may be more difficult than using multi-word maths. The problem you have... -
how to center a word on the screen?
You prolly shouldn't have put it as matthew6is2good.5, unless you have an array somewhere that tells you where each word ends and/or starts... so how would YOU know where each word ends or starts? To center a string: NumSpaces = (ScreenWidth - StringSize)/2 Where NumSpaces is the number of... -
compiler for nt based os
If you're doing Win32Asm programming, you can prolly work with hutch's MASM32 package, however I think you are probably doing DOS16 asm programming? "Information has a tendency to be free. Which means someone will always tell you something you don't want to know." -
N! up to 71 digits
Come now. N! is a LARGE number. So how do you handle large numbers which would overflow your processor's normal word, which is 32-bit? You use BCD or multi-word maths. Multi-word maths is prolly your best bet. It's up to YOU to wonder how your going to implement N!: N! is simply: product... -
Passing parameters to a procedure
That's the number of bytes to pop off IIRC. "Information has a tendency to be free. Which means someone will always tell you something you don't want to know." -
N! up to 71 digits
You have two alternatives: 1) Use BCD. The Intel 80x86 series can work with BCD. 2) Use multi-word math. The Intel 80x86 series can also work with multiple words. Personally I recommend the multi-word solution. You can find some multi-word maths stuff on this forum in threads dukely started... -
Array problem
How sure are you that the _Putstr macros, as well as the PutDec routine, don't trash di? "Information has a tendency to be free. Which means someone will always tell you something you don't want to know." -
Array problem
Where's the PutDec routine? "Information has a tendency to be free. Which means someone will always tell you something you don't want to know."
