Perhaps you could work on the indentation to being with. It might help you follow the code flow.

What are you forgetting here?
C Syntax (Toggle Plain Text) 
  1. for(j=0;j<41;j++)
  2.  for(i=0;i<79;)
  3.  txt[j][i]=32;
Hint: it's an infinite loop . . . .

[edit] And it's a lot easier to use character constants like ' ' and '\r' in your code instead of magic numbers like 32 and 13, don't you think? [/edit]

Well, I should say that, I don’t even understand on what your are trying to do here. You will have to give some more information. And your code i just such a lot of mess. You are using stuff which you shouldn't be. Few which i pointed out.

1. Using a very old compiler
2. for(i=0;i<79;) --> why are you not incr i ( include i++)
3. goto <-- dont you know that these statement shouldn't be used. Its a bad programming practice.
4. gotoxy is not a standard C function
5. and clrscr getch !
6. Code indentation is horrible. But I thought this time I will do it for you
