    system() help

    Ok, i decided to start on my mud (which is comming easier than i expected BTW...) and im trying to make it write to a file but i keep getting errors trying to clear the screen and pause the screen... i looked on google and the websites said to use:
    Code:
    system("PAUSE");
    
    and
    
    system("CLR");
    but that just gives an error... anyone know how to do it?

    Its really bad to use system calls, you should try to never use them because they spawn another process to do the work for you. read the tutorials on cprogramming.com

    Here is an example to freeze the screen, use on your header files as #include conio.h
    then, when you want to hold the screen, type the command getch(); this will wait for the user to press a key, although I would advise you putting somthing like
    "cout << "Press a key to carry on", then under getch(); put cin.ignore(); then it will not read the key the user has pressed.

    As for clearing the screen, I would go with the above advise, I do use system("cls"); but am looking into ways to rectafy my code

    I know for a fact that one call is clrscr(); but i have only ever gotten it to work with the borland compiler (On windows that is). Whenever i use MSVC i use system("cls"); as well... but clrscr() does exsist if you use borland.

    I heard that it is unwise to use system processes coz for some reason they might not exist,but i dont know if it is true is pause an external command? if it is,than is is possible that pause doent exist causing your program to malfunction or something. Just my opinion, im still pretty green so i dont know if im talking rubbish.

    search the boards and read the FAQ and look through the tutorials, system calls are NOT good to use, im seriouse this has been answered tooooooooooooooooooo many times and there doesnt need to be another thread on it.
