colon vs semicolon in loops

[jfh]

How does one get Maple to display some but not all of the results in a loop? 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:

Thank you. I need only add that even saying "print(n^3):" to end the command with a colon would still get the value of n^3 printed. Replacing print with lprint, or printf with a suitable format, would also overrule the colon.
