Error "exception not permitted here" when putting EXCEPTION in a loop

[Trish Cayetano <trishacayetano@gmail.com>]

Hi, 

I am getting error "exception not permitted here" when running below in a loop. 
Well it runs if I put it outside the loop but I need it inside the loop... 

           exception
            when ADA.IO_EXCEPTIONS.DATA_ERROR =>
            Ada.Text_IO.Put_Line ("Try a number from 1 to 4, Buddy");

Thanks in advance for your help...
