applications in any /4-bit version of Windows

Required Setup for 32-bit Applications0irst" you must install %isual +tudio $ 1 and select the C22 language option %+ $ 1and %isual C22 $ 1 3xpress both include the current version of the *icrosoftssembler .ou can verify that the *icrosoft ssembler is installed by looking for thefile ml.exe in the \vc\bin folder of your %isual +tudio installation directory" such asc:\Program iles\!icrosoft "isual Studio #$.x\vc\bin.

Building a Sample Assem"l& anguage Program

Bow you're ready to open and build your first pro ect

(pening a Pro)e t

%isual +tudio and %isual +tudio 3xpress reAuire assembly language source files to belongto a project " which is a kind of container pro ect holds configuration information suchas the locations of the assembler" linker" and reAuired libraries pro ect has its ownfolder" and it holds the names and locations of all files belonging to it We have created asample pro ect folder in the c:\Irvine\cxamples\ch03 directory" and its name is Project

Do the following steps" in order5

1 +tart %isual +tudio$ 0irst you will open an existing %isual +tudio pro ect file 9f you're using %isual

+tudio" select 0pen Pro4ect from the 0ile menu (r" if you're using %isual +tudio3xpress" select 0pen " and select Pro4ect5Solution.

# Bavigate to the c:\,rvine\&xamples\c)$3 folder and open the filenamed Pro4ect.sln

4 9n the Solution Explorer window" you will see the word !ro ect This is the nameof a %isual +tudio pro ect

) Bext" you need to add a source code file named main.asm to the pro ect To dothat" right-click on Pro4ect " select Add " select &xisting ,tem " select main.asm "and click the Add button to close the dialog window 6.ou can use this seAuenceof commands in the future to add any asm file into a pro ect 7

/ Bext" you will open the main asm file for editing Double-click the filenamed main.asm to open it in the editing window 6%isual +tudio users may see a
