I tried to mail this but it bounced back so:
	atoi("1234") will work like it has been pointed out.
The only problem with that is that you don't get any error checking other
than a return value of 0 in which case you don't know if you parsed
zero or there was an error.  On the other hand

int rcode, num;
char *s;	/* the string to parse */
	rcode = sscanf(s, "%d", &num);

will work and give back a reliable error code (rcode==1 -> conversion OK
rcode == 0 -> no conversion.
