InputString

InputString

interactively reads in a character string.

InputString[prompt]

requests input, displaying prompt as a "prompt".

InputString[prompt,init]

in a notebook front end uses init as the initial contents of the input field.

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 Wolfram System 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, the Wolfram System 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 options for InputField can be given directly as options to InputString to control the properties of the input field.
InputString[prompt] is equivalent to InputString[prompt,""].
