自己做了一個C程序，從C轉匯編，希望對你有用：
#include <stdio.h>
#include <stdlib.h>
void main()
{
char mon[12][4];
sprintf(mon[0],"%s", "Jan\0");
sprintf(mon[1],"%s", "Feb\0");
sprintf(mon[2],"%s", "Mar\0");
sprintf(mon[3],"%s", "Apr\0");
sprintf(mon[4],"%s", "May\0");
sprintf(mon[5],"%s", "Jun\0");
sprintf(mon[6],"%s", "Jul\0");
sprintf(mon[7],"%s", "Aug\0");
sprintf(mon[8],"%s", "Sep\0");
sprintf(mon[9],"%s", "Oct\0");
sprintf(mon[10],"%s", "Nov\0");
sprintf(mon[11],"%s", "Dec\0");
int a = getchar()-48;
int b = getchar()-48;
a = a*10 + b;
if(a<=12)
{
printf(mon[a-1]);
}
}
