BUILT-IN MATHEMATICA SYMBOL

Monitor

generates a temporary monitor cell in which the continually updated current value of mon is displayed during the course of evaluation of expr.

Monitor[Table[e, {x, ...}], x] generates a monitor cell that shows the continually updated current value of x during the evaluation of the Table.

In a notebook, the monitor cell normally appears directly after the cell in which Monitor is evaluated. The cell is deleted as soon as the evaluation of expr is complete.

If Print, PrintTemporary, or similar output is generated before the evaluation of Monitor begins, it will appear before the monitor cell.
