Creating Source Files
Unfortunately, Visual Studio 6.0 does not have a default ASM file type, but
you can use the Text file type instead.
Creating a New ASM File
- Select New from the File menu.
- Click on the Files tab.
- Select Text file, and enter the name of the file you want to create.
Make sure it is eight characters or less, and add the .ASM extension. Enter
the directory where you want to save the file. Here is a sample:

- Click OK, and you can now begin to type the file.
Opening an Existing ASM Source File
When creating a new program, it's often easier to just open an existing ASM
source file, delete the lines you don't want, and save the file under a new
name. Here's what you do:
- Select Open from the File menu.
- When the file open dialog appears, navigate to a directory containing ASM
files. In the filename box, type *.asm. A list of all ASM files
will appear. Select one, click on the Open button. Here is a sample,
pointing at the C:\Irvine directory:

Now all you have to do is select Save As.. from the File menu
and give the program a new name.
