* This range class started out as just that - a range class for pairs   *
* of lptr's, but ended up as a class for defining a block more than a   *
* range. The block is set by the use in Borg, and then the block can be *
* undefined, exported as txt/asm, decrypted, etc. All of this was added *
* in Borg 2.15                                                          *
