Now that you have posted your homework assignments, what are you asking from us ?

what operating system ? what version assembly language? what assembler?

Essentually you have to open two files -- input file for input and result (output) file for output. In a loop, read a...

what you are doing is attempting to print the binary value of the number. It has to be converted to ASCII before it can be printed. If you look at an ascii chart...

my guess is the screen is not 24x79. Try increasing the value of dx to test that out unless, of course, you have already thought of that and tried it.

>>What I am trying now is to reduce the number of lines.
That doesn't mean you have a poor program. Pure assembly programs are typically very huge.

one way to do it is to write a small program...

how to draw a line depends on the operating system. If you are using MS-Windows you can use the win32 api graphics functions. If you are in MS-DOS you could probably just use a line drawn with...

did you try any of these google links (http://www.google.com/search?hl=en&q=sparc+assembly+programs)?

>>may you explain it plaese ?
If you look at a standard ascii chart (http://www.asciitable.com/) you will see that the letter '0' has a decimal value of 48. So, to convert a binary value all you...

Well I think you are making things worse, not better. Here is one way to do what you want. I have not assembled or tested this.

JMP Count
CMP al,'Z'
JMP Count
LOOP TOP

The jumps are incorrect -- please see my previous post. jmp instruction is an unconditional jump meaning that the program will go regardless of any...

cmp al,'A'
CMP al,'Z'
JMP Count


you have to put a jump after every comparison -- see my previous code for example.

>>LOOP TOP
you can not use that construct in this program because you...

That loop needs to check for al = 13H ( <Enter> key) to stop the loop. As coded now the loop will never stop.

>> Mov bl,al
Why do that? just use al for tests



cmp bl,'A'

JGE Count

I got into the habbit of pushing all registers that I want to save before calling any interrups or functions because (1) general purpose registers ax, bx, cx and dx are subject to change without...

xor ax,ax
is the same as this
mov ax,0
except that xor is a tiny bit faster

I think it should be something like this -- I didn't assemble or test it.
;
mov bx,1 ; row counter
loop_start::
xor cx,cx ; column counter
l1:
mov al,'*'
mov ah,0eh ;prints to screen
int...

you need two counters -- the first counter counts the number of lines to be printed, the second counter counts the number of stars that are printed on the current line. Your code is putting a CR/LF...
