SYNOPSIS string invert_bits (string str) DESCRIPTION Invert the status of all bits in bitstring and return the new string. Note that the total number of bits (ie the string length) stays the same. EXAMPLES string s; s = set_bit("", 3); s = set_bit(s, 4); s = set_bit(s, 15); --> s is now "8 (" invert_bits(s) --> returns "G_W" SEE ALSO set_bit(E), clear_bit(E), test_bit(E), last_bit(E), and_bits(E), or_bits(E), xor_bits(E), count_bits(E), copy_bits(E)
