Query/400 dilemma?

[Tim Truax <truax@xxxxxxxxx>]

Hi All,
Question:  I have a simple transaction file (physical file) I have to
process for a report, this file is sequenced by CUST# then CCYYMMDD.
Now for the summary query reporting on the CUST#, I want get the (MIN)
and the (MAX) in the CCYYMMDD field (column) so I can do the math in the
query using the 2 fields (MIN) and (MAX) in order to arrive at the
number of days we've done business with this Customer.  Suggestions
appreciated on how I convert the (MIN) and the (MAX) to useable field
names within the query.
TIA
