interactively reads in a character string.
requests input, displaying prompt as a "prompt".
in a notebook front end uses init as the initial contents of the input field.
- 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,""].
