Question: Show more than result in a for loop

The variable A is a matrix in Maple. I need to show A, A^2, A^3, ....., A^19, A^20, and that i do by making a for loop:

for n to 20 do A^n end do

And it works and shows correct results.. 
But i want to show more than just the result of each step in the for loop. 
The result right now is without variable name etc. How can i show more than just the result ? ... 
I have changed the Typesettinglevel to extended.
Please Wait...
