Note: The problem users now face is that the 64-bit Windows versions do not have
DOS inbuilt into them. Thus, the 16-bit MASM will not run in the 64-bit versions of
Windows Vista, Windows 7, and Windows 8. The solution for this is to install DosBox
and use MASM in it. DosBox is an emulator for a PC with built-in DOS. It simulates a
PC with an older operating system, and hence, DOS programs can run on it.

i) Download DOSBox and install it.
ii) Go to the webresources of this book for a detailed guidance on how to use MASM
on DOSBOX.
iii) Guidance for this is also available in many other sites on the web.
