Input(MaxCharactersToGet)

Input returns at most 'MaxCharactersToGet' character(s). The characters are taken from the console, that is someone has to type them!
More characters might be typed in, but only the first 'MaxCharactersToGet' of them will be retained. The user has to press the Return key to end an entry.
Input cannot be used in Web programmes as all the characters available from the console (standard input for techies) have already been pumped in, in order to retrieve any form field.
Using Input in a Web script would stall it.

Return value:
A string, typed in by the user.

Example

a = input(20) $
print(a$)

(The user has to type something now!!)
hello!
