I'm having trouble trying to find a tutorial on creating WIN32 console programs, I have just about got the hang of making DOS programs and creating simple WIN API programs, and would like to try something new. Any help appreciated.

i also wanna do that, but don't even know how to get input, or output, i know how to make the console, do like this

1. Open your included folder, and copy "win32ax.inc" to "win32console.inc"
2.. Edit the first thing "format PE 4.0" to "format PE console" in the file "win32console.inc"
3. your ready!

example on how to do it with the console

include '%fasminc%\win32console.inc'
.data
hello db 'hello world',0
.code
start:
invoke MessageBox,0,hello,hello,MB_OK
invoke ExitProcess,0
.end start

if you want to work with console - use crtdll.dll or msvcrt.dll(C runtime libraries). You will find many help about it in the net and not only
look at this is example as begining.

Code:

;fasmw 1.57 console program
format PE CONSOLE
entry start
include '%fasminc%\win32a.inc'

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; macro section

struc dc [data] {
common
  .data db data,0
  .size = $-.data-1
}

macro write str {
   invoke  WriteFile, [hout], str, str#.size, temp, 0
; invoke  WriteConsole, [hout], str, str#.size, temp, 0
}

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; initialized data
iglobal
  _hello       dc 13,10,'Hello, world!',13,10
endg

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; uninitialized data

     write   _hello

finish:
