How to create a constant string - rt-2 - 26.01.2017

How to create a constant string?

I am trying

Код:

new const INV_OBJ_menuTitle[] = "Inventory";
new dialog_title[64] = INV_OBJ_menuTitle;

and I get the error: error 008: must be a constant expression; assumed zero (on the second line)

but when I try

Код:

const INV_OBJ_menuTitle[] = "Inventory";
new dialog_title[64] = INV_OBJ_menuTitle;

I get the error: error 001: expected token: "=", but found "[" (on the first line)

How am I supposed to set a constant string, is it possible?

Thank you

PHP код:



static const INV_OBJ_menuTitle[] = "Inventory";

Thank you,
But in the documentation, it says that the variable with a static scope would only be available for the script in the same "section" it was created, does anyone knows what that means a "section" refers to?

It means a block of code, the code between the two "{}", which defines an independent scope

Код:

static const INV_OBJ_menuTitle[] = "Inventory";
function(attr1)
{
     new dialog_title[64] = INV_OBJ_menuTitle;
}

This is not working, I am still getting "error 008: must be a constant expression; assumed zero" (on fourth line)

Note that I am setting up the variable at the top of my script and trying to use the constant value in a function/callback.

Thank you

No. That's something else entirely. A section basically refers to the file itself, e.g. a global static variable in an include file will only be visible to that file. There is also a directive #section that can be used to declare multiple sections within a file, but that doesn't work. Perhaps it is fixed in Zeex' compiler.

PHP код:



static const INV_OBJ_menuTitle[][] = {"Inventory"};

function(attr1)

{

     new dialog_title[64] = INV_OBJ_menuTitle;

}

Can you test before posting?
It gives the same error.

Of course a constant can contain a string. Stop being rude when I'm trying to help you. -.-

PHP код:



#define title "Invetory"

function(attr1) 

{ 

     new dialog_title[64] = title;

}

working fine with basic warnings.
