DOS 'text editor' in C++

[magicyte]

I created this DOS 'text editor', if you will, in C++ for Windows XP. Yeah, don't say anything about the 'indenting'. It sucks. Hey, once you start up the .exe (I am providing it in the attachments section if you don't have a compiler that accepts my code), maximize it so that it fits the WHOLE window (just like DOS usually does). This way it is easier to use it.

Here is the code:

magitext.cpp

#include "stdio.h"
#include "stdlib.h"
#include "alt.h"
#include "magitext.h"

int main(void) {
    x=1;
    y=3;
    z=0;
    makelayer(0,0,80,3,WHITE,GRAY);
    makelayer(47,0,80,3,WHITE,GRAY);
    makelayer(3,0,1,44,LIGHTGRAY,LIGHTGRAY);
    makelayer(3,79,1,44,LIGHTGRAY,LIGHTGRAY);
    makelayer(3,1,78,44,BLACK,WHITE);
    setcolor(BLACK,GRAY);gotoxy(0,0);align(RIGHT,"Copyright 2008 - A.C.W.");
    setcolor(WHITE,GRAY);gotoxy(0,1);align(CENTER,"Magitext");
    gotoxy(1,48);
    setcolor(WHITE,GRAY);printf("Backspace=");
    setcolor(BLACK,GRAY);printf("backspace, ");
    setcolor(WHITE,GRAY);printf("Enter/Return=");
    setcolor(BLACK,GRAY);printf("carriage return, ");
    setcolor(WHITE,GRAY);printf("Esc=");
    setcolor(BLACK,GRAY);printf("exit");
    setcolor(BLACK,WHITE);
    gotoxy(1,3);
    typeText();
    return 0;
}

magitext.h

void makelayer(int top,int left,int width,int height,int col,int bg) {
     setcolor(col,bg);
     for(register short signed int i=top;i<(height+top);i++)
     {
           for(register short signed int j=left;j<(width+left);j++)
           {
                 gotoxy(j,i);printf(" ");
           }
     }
}

short signed int x,y,z,br[23];

signed int typeText(void) {
x = getx();
y = gety();

do {
    key.c = getch();
    key.i = (int)key.c;
    
    if(key.i != KEY_ENTER && key.i != KEY_BACKSPACE && key.i != KEY_ESC) {
        if(x < 80) {
             if(x == 79 && y < 46) {
                 br[z]=x;
                 y++;
                 z=y-3;
                 x=1;
                 gotoxy(x,y);
             }
             if(x < 79 && y < 47) printf("%c",getc(key.i));
        }
    }
    
    x = getx();
    y = gety();
} while(key.i != KEY_ENTER && key.i != KEY_BACKSPACE && key.i != KEY_ESC);
switch(key.i) {
    case KEY_ENTER:
         if(y < 46) {
             br[z]=x;
             y++;
             z=y-3;
             x=1;
         }
         break;
    case KEY_BACKSPACE:
         if(x > 1) {
             x--;
             gotoxy(x,y);
             printf(" ");
         }
         else if(x == 1 && y > 3) {
             y--;
             z=y-3;
             x=br[z];
         }
         break;
    case KEY_ESC:
         exit(0);
         break;

The .exe is in a zip file below. Any comments? Please, I know it's bad. That's why I'm posting it.
