Thanks guys, these answers are very interesting, though I am not sure if I do understand everything. I'll try to sum up in my own words.

The first answer "the value assigned to b is the entry in m[a,1], not a reference to its location" shows that Maple clearly does thing a bit different than Mathcad. It's just that one has to know that.

In the second answer, using ' ' the assignment is not to the value, but to the expression. In that case, only when the expression is evaluated, then the result is given.

Interesting...

The use of math container is something I have seen in an example as well, probably it's the best way for showing values with units (which I am doing here).

Any idea how I could format the output? Right now it looks like that, however I'd like to have just 1 digit after the decimal delimiter.

Just wanted to add one more thing.

Originally my problem was that I first entered a 2D math expression, and when running the program this was evaluated. As I just wanted the text, I thought I'd need a text area or label to do that. Found out that I can change a 2D math expression to not be evaluated, so I am going for that one.

Just for the records - Mathcad behaves different.

I've actually found out by myself.

Looks like the apostroph I was using was a wrong one.

` is not the same as '

`f__α`

is actually working, so I can use a 2D defined variable in 1D.

Found out how to do it the other way around also.

assign(`f__α,β`, 1)

I'm sorry, I was a bit quick here. I've done some more tests, and I'm still struggling to make use of the variables in both 1D and 2D notation.

Here's an example where I once define a variable in 2D and try to access it both in 2D and 1D notation. And afterwards the other way around, where I do define the variable first in 1D, and try to use it in 2D afterwards. The problem in the second part is that I can't use the greek alpha.

First of all, thanks for the answer.

When running your program I got an error message first. Found out that you had a typo in your first line (opaquemodulues, should be "opaquemodules".

There are a couple of questions in my head, and part of it is that I am not using the exact library as in the example. But I will keep using this example as long as it serves the purpose of understanding.

My next question is - when loading the module with "with(AISCShapes)" the result I am getting is [Property].

Where did you find out that there is a "AISCTable" - or is this a reserved keyword?

In the example there is just the "Property" keyword used as far as I can see.

Cw := Property("W10X54", "Cw");
Property("W10X54", "Cw", "metadata");
