| SYNOPSIS | |
| string invert_bits(string str) | |
| DESCRIPTION | |
| Invert the status of all bits in bitstring <str> 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" | |
