No, that shouldn't be acceptable.  Sounds like he is using JPI.  It does
really strange things if you try to enter a non-numeric character when
it is reading a number.

The solution is to read everything as character strings and then use the
string conversion functions to convert to whatever it is you expected to
read.  They usually have some sort of error flag so you can detect when
bad data was typed.
