I found many examples use 'win32a.inc' , but I don't have one.
Can you tell me where to download?
Thanks.

download fasmw package, in include folder

And if it still asks for it, you should add this to your fasmw.inc. (if your fasmw path is c:\fasmw):

[Environment]
Fasminc = c:\fasmw\include

For some people it is not an easy thing to locate the files he/she has downloaded and then decompressed to a previously created folder, and then run fasmw.exe once to let it create fasmw.inc file, and then set up the environment in that file, so
i whould suggest Privalov to put the code in the compiler
u know, when they execute it first time, it uses "paramstr(0)" - ( the location of itself ) \ include directory as default directory location, so this way newbies won't be facing this kind of problems
