copied!<p>I am new to assembly and I am trying to make a program that counts up to 10,000 and exits. I am using fasm `</p> <pre><code> include 'include/win32ax.inc' .data inchar DB ? numwritten DD ? numread DD ? outhandle DD ? inhandle DD ? strFormat DB "Number %d ",0 strBuff RB 64 .code start: ;set up console invoke AllocConsole invoke GetStdHandle,STD_OUTPUT_HANDLE mov [outhandle],eax invoke GetStdHandle,STD_INPUT_HANDLE mov [inhandle],eax ;loop starts here mov eax, 0 LoopStart: add eax,1 invoke wsprintf, strBuff, strFormat, eax ;convert number to String. ;the number eax is now in string form in strBuff ;find out the string length of strBuff mov ecx,-1 mov al,0 mov edi,strBuff cld repne scasb not ecx dec ecx ;ecx is now the length. invoke WriteConsole,[outhandle],strBuff,ecx,numwritten,0 ;write to console ;loop cmp eax, 10000;loop compare jne LoopStart;jump to start of loop invoke ReadConsole,[inhandle],inchar,1,numread,0 ;give the user a chance to read console output before exit invoke ExitProcess,0 .end start ` </code></pre> <p>It is supposed to print Number 1 Number 2 Number 3 etc. but instead it prints Number 2 Number 2 Number 2 Number 2 Number 2 etc. for a while then exits, without waiting for the users input. what is wrong with my code?</p> <p>Edit: I got it to work! The working code:</p> <pre><code> include 'include/win32ax.inc' .data inchar DB ? numwritten DD ? numread DD ? outhandle DD ? inhandle DD ? strFormat DB "Number %d ",0 strBuff RB 64 number DD ? .code start: ;set up console invoke AllocConsole invoke GetStdHandle,STD_OUTPUT_HANDLE mov [outhandle],eax invoke GetStdHandle,STD_INPUT_HANDLE mov [inhandle],eax ;loop starts here mov eax, 0 LoopStart: add eax,1 mov [number],eax mov edi, eax push eax invoke wsprintf, strBuff, strFormat, edi ;convert number to String. add esp, 4 * 3 pop eax ;the number eax is now in string form in strBuff ;find out the string length of strBuff mov ecx,-1 mov al,0 mov edi,strBuff cld repne scasb not ecx dec ecx ;ecx is now the length. push eax invoke WriteConsole,[outhandle],strBuff,ecx,numwritten,0 ;write to console pop eax ;loop mov eax, [number] cmp eax, 10000;loop compare jne LoopStart;jump to start of loop invoke ReadConsole,[inhandle],inchar,1,numread,0 ;give the user a chance to read console output before exit invoke ExitProcess,0 </code></pre> <p>.end start </p>
