I have done a time-consuming run and calculation. After many hours ( about 7 hours!), the black color which shows that the cell is evaluating, turn into gray and a strange text appears like this :

(Dialog) Input[157]:= (* my code in the cell *)

Does anyone know what it is and why this is happening ?!

    $\begingroup$ This means that you have interrupted the calculation. Most likely you did not do this through using the Dialog function but by using the Evaluation -> Interrupt Evaluation item or accidentally pressing the corresponding shortcut key. You can resume by evaluating Return[]. $\endgroup$

  • $\begingroup$ @ Szabolcs : As you said, I haven't used Dialog function and it the notebook was evaluated by Evaluating function. You mean that there is no error in my code and it was just a coincidence ?! Because it's a long code with a huge load of lists of number! $\endgroup$

    $\begingroup$ This is a clarification to those who came to Mathematica since version 10: in v10 the Interrupt Evaluation menu item was removed, though the shortcut key (Option-Command-. on Mac) still works. $\endgroup$
