Casio Graphical Calculator Encyclopaedia

Token: ?
Type: IO function
["<text>"]? -> <var>


Prints "<text>" on the text screen if given, followed on the same line by "?". The calc then waits for the user to input a value or expression and press [EXE]. This value is then assigned to the variable <var>.

Other information:

Should the user input an incorrect expression, a Syn error occurs. Pressing the left arrow key, however, will allow the program to continue by clearing the text screen and waiting for the user to enter a correct expression in the same way.
