Given:


Table | A/C#  | Ref   | Date                        |
       | CHECK | CHECK | _d, CALC TODAY - _d as Days |

Table | Dr                      | Cr    |
       | _d, CALC _d - _c as Bal | _c    |


   Q1. What, if any, sorting?
   Q2. Change CHECKs to CHECKPLUSs. Repeat Q1.


What I'm seeing:

   A/C# and Ref: sorted.
   Bal:          not sorted.
   Days:         sorted if CHECKs, not if CHECKPLUSs. <== Why ?

It would appear stupid to ever use CHECKPLUSs but it might be 
significant someplace else.
