I have a little program from K&R:

#include <stdio.h>

int main()
{
 int c;

 c=getchar();
 while (c != EOF){
   putchar(c);
   c=getchar();
   }
 return 0;
}

When I run it from within RHIDE 1.4.7, it works fine: A DOS box opens, I
enter some characters, hit Return, and the characters are echoed. Now,
I'm not sure what the EOF character should be, but I am thinking Ctrl+Z.
This works and I am back in the RHIDE editor. But, when I try to run
again with Ctrl+9, the program exits with: Program exit code; 0
(0x0000), before I get any chance to put in any input. No DOS box opens,
nada.

Can anyone explain why this happens? What should I do to get the
expected behavior?
