printlevel

It's the semicolon at the end of the `end do;` that is controlling whether the output from statements within the for-loop get displayed or not. See the help page ?printlevel for some more on controlling that for nested loops.

For a string like your "--" you might want to use %s instead of %a inside printf, if you expect the double-quotes to not be displayed.

The single right-quote ' is sometimes called an uneval quote. It can wrap objects like names, function calls, etc. But the minus sign is not an object, and Maple will issue an error on being handed '-'. The single left-quote can be used to make a name out of symbols, and so is sometimes called a name quote. Hence `-` is a name (it's actually the protected name of the prefix minus operator).

If I read ?printlevel right, I can either display everything, or nothing, inside the do loop. For now, that's OK. As long as it does what I expect it so I can make it do what I want (as with any programming language, I guess).

Can I display a k_1 (k with a 1 subscript) string, k_2, etc? I tried a few combinations of %12s/a and quotes, right-apostrophe and left-apostrophe, but could not get it to work.

Thanks.
