Hi Mark,

>I changed all four index expressions to BINTOC( ... ), reindexed, refreshed the view in file explorer and expected the CDX file to be smaller, but it wasn't--exactly the same # of bytes.

An integer takes four bytes in an index and the table. BINTOC() creates a 4-character string which also takes 4 bytes. You can't compress an integer index any further.
