I'll add my 2 cents of answer relating to your sentence

Thanks, but I rather want them to be returned on two separate output lines, if that's possible.

As mentioned by Szabolcs functions always return a single answer. Therefore, if you want more than one answer in a single return, you need to return a single answer that can contain multiple elements, and this was already mentioned earlier, with several suggestions for different containers.

If you need to create a cell, you can print (Szabolcs already mentioned that) of your more fancy cell generation using CellPrint and related functionality. Anyway, printing or generating cells is considered as Side Effect of the function, since it is not the value returned by the function, but "something" that is done "on the side" (just compare Map to Scan to notice the difference)

I hope it helps to summarize the issue

sincerely

You are conflating output lines you see during interactive work with return values of functions.

Functions are building blocks of programs. So is the Module construct (which is technically a function in Mathematica). They return precisely one value. The purpose of functions is to be able to engineer a larger program in a structured, readable and maintainable manner.

If you are working interactively, and want to see the output right away, then you do not need Module.

If you are looking for a command that explicitly instruct the system to output something into a notebook, and can be used as part of a larger program, see Print.

Thanks! That's right. Actually there is no grey multiplication sign on my notebook, and that was my source for confusion.

Another question then arises:

Is there any way to use Module and still show the output of two different commands, as I tried to do on the original post?
