I hate crap like that.. it's been working for 30 years by accident, or it 
doesn't work and they don't know that.. either way, I'd never do it that 
way.. I'd never even think to do it that way.. it's probably based on some 
theoretical thing that Dan or Mike put in one of their books :-)

This one's been working for 30+ years but I can't write a unit test
until I know exactly what it is meant to be doing:

Query

Debtor |   A/C#   |  MyRef   |    Dr    |      Cr      |
        | check _a | check _m | check _r | blank        |
        | _a       | _m       | blank    | _r, calc sum |

Endquery


Any ideas?
