INPUT

    INPUT is used to enter an expression from the keyboard and place the
    result in a specified memory variable.

Syntax

    INPUT [<prompt>] TO <memvar>

Argument

    <memvar> is the name of the memory variable where the result of the
    evaluation is placed.

Usage

    INPUT takes entry from the keyboard as an expression of any data type.
    It then evaluates it placing the result into a newly created memory
    variable of the same data type.  Pressing Return confirms entry.  If
    Return is the only key pressed, INPUT terminates but does not create
    the memory variable.  Note that Esc does not terminate INPUT.

    Entering an invalid expression generates a runtime error.
