Details and Options Details and Options

InputString returns what it reads as a string, without evaluation.
The operation of InputString may vary from one computer system to another. When a Mathematica front end is used, InputString typically works through a dialog box.
When no front end is used, InputString reads from standard input.
If the standard input is a file, then InputString returns EndOfFile if you try to read past the end of the file.
On systems with textual input, InputString[] uses as a prompt.
When InputString is evaluated, Mathematica stops until the input has been read.
With a notebook front end, InputString by default puts up a dialog window with a standard appearance.
The prompt given can be text, graphics or any expression.
InputString takes notebook options. The default settings include WindowFloating->False, WindowSize->All, and WindowTitle->None.
InputString by default puts up a dialog in the middle of the main display screen. Explicit settings for WindowMargins override this.
The option FieldSize can be used to specify the size of the field used for input.
InputString[prompt] is equivalent to InputString[prompt, ""].
