I am not at 400 so I not remember the command structure.
Basically you want to define a CURSOR which has all the relevant fields of
the file,
then you want to read the records in the SEQUENCE of dollars decending
Your RPG code increments by one each time the SQL reads a record
then output again with that rank before reading next record.

I suspect that from a performance standpoint, it might be simpler to do the
whole thing in RPG & forget SQL.  What I would do is create a temporary
logical which sequences the records in descending dollar, read each & update
each with rank assigned, then kill the logical.
