Hi,

I'm following example A  here https://gambas-buch.de…=k29:k29.3:k29.3.3:start

e.g.

but get an error 'unknown Identifier: Matrix'

Matrix - as I understand it is part of the gb.gsl component https://gambaswiki.org/wiki/comp/gb.gsl

I'm assuming this component is loaded by default as I can't find in in Project|Properties|Components

Or is something else going on that I don't understand? (highly likely)

You are assuming wrong. You always activate components yourself, unless you loaded the source code into IDE, then it should be activated.
You can't see them because, default, they are not shown as they are deprecated.

Try, in project properties (tab components) clicking where arrow points to, and the mouse pointer is, to show them.  

 Thanks for the tip, however clicking show depreciated does nothing, no new components are shown????  Do you know what replaced it?

Are you sure gb.gsl is depreciated, because the wiki doesn't show it as being depreciated, only partially implemented.

Does gb.gsl show up in your project properties as being depreciated, because mine (old Gambas version) shows it as "not finished, but stable".

If it is actually depreciated, then the wiki needs updated. If the wiki is correct, then the project properties in the newer Gambas version is incorrect and needs corrected.   :?:

What version of Gambas are you using?

 Is it just greyed ?

They are grey if they are incomplete, unstable or just unfinished.
You should still be able to select it. Its not disabled b cause it's grey.

Aah no i see it is not greyed.

Is it installed?
For apt packager try this..
sudo apt install gambas3-gb-gsl

What Gambas are you running? And I mean from where, what repository, what version?
Send some system info output as well (menu ? -> System Information -> click Copy and Paste here), without info no clue what can be going on.

Good one Bruce.
Deprecated components are not part of a default Gambas3 install and must be installed separately, before you can use them.

That did the trick - Thanks Bruce and everyone else for their suggestions. :-)

Your arrow is pointing to the gb.sdl component, not the gb.gsl component.

Maybe you should run everything past Poly first. He does a great job of catching your mistakes.
