To all expert :
Need some help again
Let said .....i would like to get input from user, and i would like limit their input, my code as below :
print "Please enter 1-60\n";
$option = <STDIN>;
For this case,let say user input a or b or 90 or 100, this code will reject it, and ask the user re-enter again. So, how can i make this ?? any help from you guy ?

Thanks !
