If I use a code of this type:

Table[foo[i], {i, 0, 10}]

Mathematica won't output anything until it is done: is it possible to know at which point of the calculations I am, without using some slow For loop (in this way it would be easy to print something like i=1, i=2...)?

I want to check if everything is OK at each step.

    $\begingroup$ Table[n = i; Pause[1]; foo[i], {i, 0, 10}]; Labeled[ProgressIndicator[Dynamic[n], {0, 10}], Dynamic[n], Right] for overkill $\endgroup$

The simplest way is to put a Print expression into your Table expression.

Table[Print["i = ", i]; foo[i], {i, 0, 10}]

If you only want to see the what is printed while the evaluation is running and have it automatically deleted upon completion, then use

Table[PrintTemporary["i = ", i]; foo[i], {i, 0, 10}]
