hi
I've noticed that other dos and win compilers have conio.h that contains
code for clear screen. _clrscr What is the equivalent for Digital Mars?
Thanks in advance

You could rewrite this with
int86x/int86x_real and using REGS, REGS and SREGS...
Check bios.h and dos.h

doesn't it work like that ?
may be you just have to replace int86 by int86_real

The console window peepers can do it this way.

#include <windows.h>

void clrscr()
  {
  HANDLE hout;
  DWORD nc, ncw;
  CONSOLE_SCREEN_BUFFER_INFO sbi;
  COORD home;
  home.X=home.Y=0;
  hout=GetStdHandle(STD_OUTPUT_HANDLE);
  if(hout==INVALID_HANDLE_VALUE) return;
  GetConsoleScreenBufferInfo(hout,&sbi);
  nc=sbi.dwSize.X*sbi.dwSize.Y;
  FillConsoleOutputAttribute(hout,sbi.wAttributes,nc,home,&ncw);
  FillConsoleOutputCharacter(hout,' ',nc,home,&ncw);
  SetConsoleCursorPosition(hout,home);
  }
