Hey guys, I dont know if this is the section to put this in, but this was the closest one anyway, Im trying to modify this program so it can 'fold long lines at some reasonable length'

Any suggestions??

/* vis: make funny characters visible (version 1) */

#include <stdio.h>
#include <ctype.h>

int c;
int i=1;

while ((c = getchar()) != EOF)
if (isascii(c) &&
(isprint(c) || c=='\n' || c=='\t' || c==' '))
if(i > 65) {putchar('\n') ;i = 0;}
printf("\\%03o", c);
