Simply use function atoi().

int i;

i = atoi(comando_2);

If comando_2 is an alpha string (like "hello, world") atoi() return 0.
You must test the value of comando_2 with a loop like this:

	for(i=0; i < strlen(comando_2); i++) {
		if(! isdigit(comando_2[i]) ) {
			printf("wrong value!!\n");
			exit(bad);
		}
	}
