What is a macro?

Is a macro only a placeable off?
I want to know why you do macros.

You use macros if you have the same routines, that you would like to use in more than 1 object.

This is a question I asked because I wanted to hear your explanation.
Since I am a non-English speaking person, it is difficult to understand the text and I do not understand the contents of the manual alone.
I was asking for a bit more detail.
I would be more than grateful if you could explain with an example.

So how do you create macros?
All I found was to turn off placeable, is there more?

A typical example where I use a macro, is when I want to offer different languages in the object.
The Master-Script of the object calls the Macro:

CALL "Flexi_Zone_Dictionary" PARAMETERS ALL int_language = int_language RETURNED_PARAMETERS dict_words

The Macro has the following in the Master:

DICT local IF int_language = 1 THEN local.de.raumnummer = "Raumnummer" local.de.raumname = "Raumname" ENDIF IF int_language = 2 THEN local.en.raumnummer = "Zone number" local.en.raumname = "Zone name" ENDIF DICT dict_words IF int_language = 1 THEN dict_words = local.de IF int_language = 2 THEN dict_words = local.en PARAMETERS dict_words = dict_words END dict_words

Explanation:
DICT local declares a Dictionary for the translated words.

local.de.raumnummer = "Raumnummer" is one dictionary entry for the language German (de) for the word Roomnumber (raumnummer)

DICT dict_words declares a 2nd Dictionary which is then stored in the parameter dict_words.

END dict_words returnes the values of dict_words to the calling object.

In the main object you can then replace a word in your own language by a dictionary term.
Normally you would write

TEXT2, 0, 0, "Raumname"

Now you can write

TEXT2 0, 0, dict_words.raumname

When you then change the parameter int_language from "de" to "en", the 2D-content will change its language as well. Create for this a VALUES field to let the user choose the language:

VALUES{2} "int_language", 1, "de", 2, "en"

Other examples are opening lines for windows, door closers, profiles for curtain wall windows etc.

Thank you for your answer.

But what I found was that the placeable was not checked in the macro. So, is there a macro that sets other options?

Or can I just call all gsm files and use them?

You can call all gsm-files to use them as macro. If "placeable" is unchecked, it will not be found as object in the object settings dialog. You can use a macro both as called object and in the case it is placeable as "standalone" object.
