Am I the only one who is tired of using row+column notation for cells scattered within a box???

I propose the following "box+qualified" notation be used for cells in a box: b6q123456789

Code:
 +-----------------------------------+
 |  .  .  .  |  .  .  .  |  .  .  .  |
 |  .  .  .  |  .  .  .  |  .  .  .  |
 |  .  .  .  |  .  .  .  |  .  .  .  |
 |-----------+-----------+-----------|
 |  .  .  .  |  .  .  .  |  1  2  3  |
 |  .  .  .  |  .  .  .  |  4  5  6  |
 |  .  .  .  |  .  .  .  |  7  8  9  |
 |-----------+-----------+-----------|
 |  .  .  .  |  .  .  .  |  .  .  .  |
 |  .  .  .  |  .  .  .  |  .  .  .  |
 |  .  .  .  |  .  .  .  |  .  .  .  |
 +-----------------------------------+

In the case of this grid, ronk's ALS would become:

Code:
 *-----------------------------------------------------------------------------*
 | 8       16      4       | 3       2       16      | 5       7       9       |
 | 9       16      2       | 5       1467    1467    | 146     3       8       |
 | 5       7       3       | 1468    1469    14689   | 1246    14      12      |
 |-------------------------+-------------------------+-------------------------|
 | 1       3       57      | 2       49      49      | 8       6       57      |
 | 2       9       567     | 1678    13567   135678  | 137     15      4       |
 | 4       8       567     | 167     13567   13567   | 1237    9       12357   |
 |-------------------------+-------------------------+-------------------------|
 | 6       2       8       | 147     13457   13457   | 9       145     1357    |
 | 3       5       1       | 9       47      2       | 47      8       6       |
 | 7       4       9       | 16      8       1356    | 13      2       135     |
 *-----------------------------------------------------------------------------*

Code:
old notation:  ALS-xz: (1=3)[r4c9,r5c78] - (3=1)r9c7 ==> r6c7<>1

new notation:  ALS-xz: (1=3)b6q345       - (3=1)r9c7 ==> r6c7<>1

i think its a good idea ive been using it with in my own solver.

saves some confusion on determining if the "a" or "b" is using rows/cols/ box as its defining house.

Except that 'a' (and something else too) was used for 'q', this was tried on the Players' Forums. It doesn't work out as well as one might think ... because you end up translating back to rMcN in order in order to visualize links to peers.
