[Gambas-user] Bug / changed behaviour of Input

[Emil Lenngren]

That's the difference, If you pass the string "1234" to Read As Integer,
you get the Integer 875770417, because "1234" is in ascii 49 50 51 52, and
49 + 50*(2^8) + 51*(2^16) + 52*(2^24) = 875770417.

If Input only returns the raw string, the user can do the Val on his/her
own afterwards, if he/she wants to.
In most cases (if Input simply returns the raw string),
Dim a As Integer
Input a
is good, because Input returns a String, and correct string to int
conversion is done automatically.
