FORM INPUT n AS a$

n: iexp
a$: svar

FORM INPUT and FORM INPUT AS are both used to input string variables. The value
of n specifies the number of characters to be entered, up to a maximum of 255.

Additionally, FORM INPUT AS displays the current value of a$, which can then be
edited, or taken as a 'default' input by pressing Return or Enter immediately.
The editing facilities are the same as those for the INPUT command.

Example:

    FORM INPUT 10,a$
    b$="test"
    FORM INPUT 5 AS b$
    PRINT a$,b$

--> This asks for two strings to be entered. On the entry of the second string,
    the word 'test' is displayed as a preselected value of b$. This may then be
    edited, or accepted by pressing Return.

Memo: A value of 0 for n is valid and causes the input to auto end.
