Hello.

I am a newbie to Maxima and I have a question.

I have a lot of variables: K111, K112, K113, K121, etc. And want to
declare all of them constant.

But running

for i : 1 thru 3 do
    for j : 1 thru 3 do
        for k : 1 thru 3 do
                declare( concat('K, i, j, k), constant );

Fails with

   Improper argument to declare:
   concat('K, i, j, k)
    -- an error.  To debug this try debugmode(true);

What is correct way to achive the same result as with the following?

declare( K111, constant );
declare( K112, constant );
....
declare( K333, constant );

Thanks in advance, ptomaine//
