The Maple output below displays everything done in a loop ending "end if;" and nothing done in a loop ending "end if:" but one of the two commands inside each loop ends with ":" and the other with ";". I know the output is what my program asked for but it's not what I had hoped for.

as far as I know, it is not possible to do what you want.

I'd use a ":" for the "end do:" and then use  ":" inside
the loop for the ones you do not want echoed to screen,
and for the ones you want to see, use an explicit print() on them.

for n from 1 to 2 do
      n:
      print(n^3);
od:

      1
      8
