Hello, I'm beginner with ASM so don't be harsh. I'm wondering how to display the content of PSW on standard output. I mean every single bit i.e :
CF 0
PF 1
AF 0
and so on. Actually I need to display flag registers but my first thought was to display psw because it has all I need. I would be very gratefull for every tip (ofcourse scratch of code would be quite better :) )

In the attachment a short example using the MASM32 SDK. For the flags, read up in AMD's or Intel's manuals.
MREAL macros - when you need floating point arithmetic while assembling!

Hi nerdek,

first things first: Welcome to the forum. Please check qWord's example and check the manuals. Flags are often used.

You have to know the facts before you can distort them.

Thank you very much ! Your example helped me a lot :) (PSW - program status word I thought it's common but I might be wrong)
