Control-Z is the character Windows uses in text-mode to signify
end-of-file.  When doing binary file I/O a physical end-of-file
signifies end-of-file.

SWISH-E operates in binary mode on Windows: rb, wb, rb+


Here is a simple test program...

$ cat test.c
#include <windows.h>
#include <stdio.h>
int main(void){
        FILE *fp;
        int c;
        fp = fopen("test.idx", "rb");
        while(c = getc(fp)){
                if(c == EOF){
                        return 0;
                }
                printf("%c", c);
        }
 
        return 1;
}

$ gcc test.c

$ a.exe
There is a control-z here and here and here and none are treated as
EOF.


$ cat test.idx
There is a control-z here and here and here and none are treated as
an EOF.
