First, you declare the array, no initialization.

Then, from 0 thru 11, you assign a string to each.

Like:
string aSymbol[12];
aSymbol[0]="EUR/USD"; // and so on

Variation 1

Code

STRING* asymbol[12];
str_cpy(asymbol[0], "EUR/USD";
str_cpy(asymbol[1], "USD/JPY";
str_cpy(asymbol[2], "AUD/USD";
... and so on...

Variation 2

Code

TEXT* asymbol = {
     strings =  ("EUR/USD","USD/JPY","EUR/JPY","AUD/USD","NZD/USD","AUD/NZD","USD/CAD","GBP/USD","EUR/GBP","GBP/JPY","AUD/JPY","EUR/CAD");
}

I'm not sure the syntax is totally OK, I wrote it without any editor, help or so.

my solution:

Code

#define SYMBOLS "EUR/USD","USD/JPY","EUR/JPY","AUD/USD","NZD/USD","AUD/NZD","USD/CAD","GBP/USD","EUR/GBP","GBP/JPY","AUD/JPY","EUR/CAD"
string aSymbol[12];
...
...
if (is(FIRSTINITRUN)){
   while(asset(loop(SYMBOLS))){
         aSymbol[i]=Asset;
   }
}

If it works, something really new must be implemented in GS.
Or is it a Zorro feature?

Variants 1 and 2 are wrong. The variant by Grat is correct syntax, but the loop function is normally for portfolio optimization, not for array filling. Andrew's version is correct.

Yeah, Zorro is different.
