Assignment Operators (continued)
&= Bitwise AND
assignment Integer-integer Integer a = 0b11111110
a &= 0b01010101 = 0b01010100
^= Bitwise exclusive
OR assignment Integer-integer Integer e = 0b11111110
e ^= 0b01010101 = 0b10101011
|= Bitwise inclusive
OR assignment Integer-integer Integer i = 0b11111110
i |= 0b01010101 = 0b11111111
List Operators
sizeof() Number of
elements Any Integer sizeof([1, 2, 3]) = 3
sizeof('0011223344') = 5
sizeof("string") = 6
sizeof(12) = 1
sizeof([1, [2, 3]]) = 2
*Note: the last example demonstrates that the
sizeof()
operator returns the shallow count of a
complex list.
head()
Head List Any
head([1, 2, 3]) = 1
*Note: the Head of a list is the first item in the list.
tail()
Tail List List
tail([1, 2, 3]) = [2, 3]
*Note: the Tail of a list includes everything except
the Head.
first() Returns the first
element of the list
and resets the list
iterator to the
beginning of the list List Any list = [1, 2, 3];
for( item = first(list);
more(list); item = next(list) )
{
ProcessItem( item );
}
next()
Returns the next
element of the list
relative to the
previous position of
the list iterator List Any
list = [1, 2, 3];
for( item = first(list);
more(list); item = next(list) )
{
ProcessItem( item );
}
