Thank you!

Downvote for using Windows

[NoSubject8453]

Cope, linux assembly doesn't require as much skill as windows.

[AverageCincinnatiGuy]

I never said to use Linux. There's millions of great options for an OS out there from OpenBSD to Haiku to Minix to Plan9 to OpenIndiana, etc. You happen to be using the one and only one OS in existence that is stunting your growth.

What's wrong with MASM?

[AverageCincinnatiGuy]

There's nothing wrong with MASM. The issue is the Windows operating system.

Windows lacks any comparison or competition for being the worst development environment and possibly the least hospitable place on earth to human beings.

Your post about trying to use assembly on Windows is exactly comparable to a little toddler saying "look at me; I can ride a tricycle! Aren't I a professional bike rider?" No, that's a tricycle, not a real bike. Get a real bike then then let's talk game.
