INPUT Get Input From User

Section: Input/Ouput Functions

Usage

The input function is used to obtain input from the user. There are two syntaxes for its use. The first is 
    r = input('prompt')

in which case, the prompt is presented, and the user is allowed to enter an expression. The expression is evaluated in the current workspace or context (so it can use any defined variables or functions), and returned for assignment to the variable (r in this case). In the second form of the input function, the syntax is 

    r = input('prompt','s')

in which case the text entered by the user is copied verbatim to the output.
