The procedure suggested by Marc Meketon will not work under PC-DOS, since ascii 12 is a graphics character in that system. If you are running under PC-DOS, add ansi.sys to your config.sys file with "device = ansi.sys". Then from C issue the command printf("\033[H\033[2J"); Works fine for me. Charles cib@lanl
