[Scilab-Dev] User-Input Validation

[Kalyan Chatterjea]

Hello,
I have written a simple code for User-Input-Validation. It seems to work.
But for a wrong string input there is the error 4 (Undefined variable:).

Q1. Can this error be hidden?
Q2. Kindly let me know if I should use a better validation code.

Thanks for your help
Kalyan

CODE:

clear
clc
month = 0;


while (month<1 | month>6)

    month = input('Please chose your option between 1 and 6: '); if
(type(month)==10) then month=0;end;//10 - represent string

end

select month
        case 1
            disp("Month is January")
        case 2
            disp("Month is February")
        case 3
            disp("Month is March")
        case 4
            disp("Month is April")
        case 5
            disp("Month is May")
        case 6
            disp("Month is June")
        else
            disp("Wrong Month number")

end

disp(month)
