Thanks again for pointing out the bug, I'll fix it as shown by the
few code lines below.

One thing I was wondering is: since "buf" is static, may I assume
it is filled with '\0' by the compiler?  (So there will be ne need
for me to place the terminating '\0')


itoa.c
------
/* .. */

/* old code: #define MAXSZ   21  */
#define MAXSZ   20  /* assuming integer is made of 19 digits + sign */

char *
itoa(int n)
{
   /* old code:   static char buf[MAXSZ]; */ 
   static char buf[MAXSZ + 1]; 
   char *p = buf + MAXSZ;
   /* ... */
   *p = '\0'; /* << really needed ? >> */    
}
------
