You can choose using MASM. MASM - is the Microsoft Macro Assembler. It is an assembler. It takes your code pre-processes it and converts it to binary. The links it to runnable executable or an OBJect file. All Intel processors 32bit and em64t processors (80386 and up) support the 8086 compatability mode called 'real mode'. Visual Studio includes both 32-bit and 64-bit hosted versions of Microsoft Assembler (MASM) to target x64 code. Named ml64.exe, this is the assembler that accepts x64 assembler language. The MASM command-line tools are installed when you choose a C workload during Visual Studio installation.

DOWNLOADING MASM 6.15

These instructions assume that you have Winzip.exe installed on your PC. If not, download and install it.

Now download masm.zip into some folder, and then navigate to it using Windows Explorer and double click on it.

This should bring up Winzip, and after agreeing to its conditions, click on 'Extract'. In the window this brings up, alter the 'Extract to' field displayed to 'c:masm615', and ensure that the option 'use filenames' is checked. Now click on the 'Extract' in this window, and close Winzip. This should result in the folder 'cmasm615' being created, with subfolders including 'bin' and 'programs'.

Next click on Start/settings/control panel. Then double click on 'System', select the 'Advanced' tab, and click on 'Environment Variables'. In the lower text box, select 'path', and click on the Edit button below that. Add onto the righthand end of the text which is then displayed above in 'variable value', a semicolon and then: c:masm615bin
After this, close all programs.

Microsoft Assembler X64

Now employ Start/run and type into the box: cmd
and press OK. Maximize the resulting DOS window.
Employ: cd masm615programs
This will make 'programs' the active directory. You should place all the Assembler programs that you create in this folder. The folder already contains a simple program called 'double.asm', which doubles small numbers. Compile this program using: ml double.asm
This should produce an executable called 'double.exe'.
At the command prompt, type: double
and, if everything up to this stage works, the program should ask you to enter a number less than 5.

Initializes the program memory model. (32-bit MASM only.)

Syntax

.MODELmemory-model ⟦,language-type⟧ ⟦,stack-option⟧

Parameters

memory-model
Required parameter that determines the size of code and data pointers.

language-type
Optional parameter that sets the calling and naming conventions for procedures and public symbols.

stack-option
Optional parameter.

stack-option is not used if memory-model is FLAT.

Specifying NEARSTACK groups the stack segment into a single physical segment (DGROUP) along with data. The stack segment register (SS) is assumed to hold the same address as the data segment register (DS). FARSTACK does not group the stack with DGROUP; thus SS does not equal DS.

Remarks

.MODEL is not used in MASM for x64 (ml64.exe).

The following table lists the possible values for each parameter when targeting 16-bit and 32-bit platforms:

The following example demonstrates the use of the .MODEL directive.
