INPUT  INPUT Get Input From User


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.
