[Doogee]

Ok want to happen is that when the user types in cd.. once you get to c:\windows it will take you back to C:\

Heres the source anyway :

int ver()

"=============================\n\n";
return 0;
}

// Main Function
// This contains the main features, how ever I will move the command loop
// or the commands into different function(s).
int main(char* args[], int nargs)
{
char cmdi[200]; //sets a char array for the Command Input
char cd[100]; // sets char array for the cd command
char cdcom[50]; // sets char array for the commands inside the cd command
int exitlevel; //Sets the exitlevel
int errorlevel; //Sets the errorlevel
int cdlevel;

ver(); //Prints Version.
exitlevel = 0; //sets exitlevel to 0
errorlevel = 0; //Sets errorlevel to 0
cdlevel = 0;
while (exitlevel == 0) //Starts the "Command Loop"
{ //(Which might be moved into a function.
errorlevel = 1;
cout << "C:\\>"; //Writes C:\>
cin >> cmdi; //Input thingy

if (strcmp(cmdi, "exit") == 0) // The Exit Command
{
exitlevel = 1; // Sets exitlevel
errorlevel = 0; //sets errorlevel
}
if (strcmp(cmdi, "ver") == 0) //prints the version
{
ver();
errorlevel = 0;
}
if (strcmp(cmdi, "help") == 0) //prints the help (not yet done
{ //will become help() function!
cout << "Microsoft DOS 98 Help:\nNo help availiable at this time, work it out yourself";
errorlevel = 0;
}
if (strcmp(cmdi, "credits") == 0)
{
cout << "Mostly 'borrowed' from X11's DOS XP Project and added to by Doogee - doogee@punkass.com\n";
errorlevel = 0;
}

if (strcmp(cmdi, "cd") == 0)
cout << "cd to where:specify a directory\nDirectory: ";
cin >> cd;
if (strcmp(cd, "windows") == 0)
while (cdlevel == 0)
{

cin >> cdcom;
if (strcmp(cdcom, "dir") == 0)
{
cout << "Directory contents of c:\\windows:\n";
}
if (strcmp(cdcom, "cd..") == 0)
 // This is where i want it to go back to C:\\>
}

if (errorlevel == 1) //Prints errorlevel
{

errorlevel = 0;
}

}
cout << "Thankyou for using Dos 98...\n\nKERNEL FAILURE in MCDCTRL.DLL at 0e3FF 44PGE\nContact you're hardware vendor\n";
return 0;
}

erm.....
note: the name of this category "Linux Programming".
note: the command "cd.." in DOS will already take u down a directory

I almost posted the same message and then I realized that he is just trying to make a DOS COMMAND emulator which you should be able to compile and run in Linux. It's not a bad way to learn how to program..

im just trying to make a mockery of it, although you can see it yet, but i will get to the funny stuff after i get the most common DOS commands down pat.

Also it is Linux Programming, im editing the program in gedit, comiling it with g++ and running it from a gnome terminal. in my books you can't really get more linux than that.

Doogee, fix that code (tab it out) i cant work with squshed oops you know.

meanwhile....
