\b;Instruction \c;sizeof\n;
The sizeof function lets you know the number of elements contained in an \l;array\u cbot\array;.
That is the index of the last element plus one ("empty" elements are counted).
\c;
\s;{
\s;	int a[12];
\s;	a[5] = 345;
\s;	message( sizeof(a) );  // will display 6
\s;}
\n;
In this example we have 6 elements in the array after \c;a[5]=345\n;. The non initialized elements \c;[0]\n;, \c;[1]\n;, \c;[2]\n;, \c;[3]\n; and \c;[4]\n; will be counted.

With multidimensionnal arrays you can get the size of a sub array:
\c;
\s;float xy[][];  // 2 dimensionnal array
\s;xy[5][10] = 67;
\s;message( sizeof(xy)    );  // will display 6
\s;message( sizeof(xy[5]) );  // will display 11
\s;
\n;
