Thread: clrscr(); not clearing the screen

lets say u write some program which counts to 1000 and spams 1000 lines. then it ends. then u start a new program which does clrscr(); well, on my computer, when it does this clrscr(); it only clears the top half of the command prompt window-leaving the spam visible in the bottom half

Windows xp professional
borland c++ 5.02

Code:

clrscr();

its like even tho I have my command prompt screen set so large that I spam

Welcome to the wonderful world of implementation specifics. I suspect that your clrscr function just clears an area 80x25. If your command prompt is larger, it doesn't work. Furthermore, you're on a WinXP machine, and you're running a DOS program. The command prompt for WinXP is not DOS.

There are two command prompts in XP. 'cmd' and 'command'. They behave differently. Neither one of them is true DOS.

Quzah.

so is there no way to clear it? That hardly makes it seem like XP is some kind of upgrade.

The problem is that you are using a DOS compiler to run a DOS program on a NON-DOS operating system. You cannot expect non-ANSI code to behave the same from one OS to another. It has nothing to do with XP not being a good enough upgrade. It has to do with you compiling non-ANSI code on an entirely different OS.

Yes,

system("CLS");

works


If I run this command on, say, Win 95, is it going to have a problem?
