In the mean time you can use
thisinclude stdio.h and you can use scanf from lite-c with the console version of acknex.exe
there is a dll for printing to console with printf, you do not have to use that since the original printf prints to white screen. But then it makes 2 console like screens so you can start with -nwnd and use the original black console.
or you can print to white video_screen=0 with original printf and cprintf to print to real console.(you need to comment out or edit the 3rd(last) line of printf.h tough)
edit: and oh, of course, you can use this console wihout the video_screen 0, you can both have the console and the engine window
