Re: Same prefixes (was Re: It's That Time Again! etc.)

Doug,

You're right this is not an internally/externally described file issue.
Prefixed databases are not uncommon.

What you're advocating has merit.  Whether "prefix dropping" would be a $10
or $20 enhancement only the Toronto folks can say.

Rather that converting your data files (dropping prefixes) and adding
PREFIX() to your programs,  you could instead create new LFs using the
RENAME keyword.  Access path sharing would make the overhead minimal.
