[pilot-db-list] Re: calculated field

[Scott W. <swa...@my...>]

I have just implemented this.  It is not quite circulating yet, but will
be very soon.  The function to access fields from other records is called
"fld" it takes 2 arguments both integers.  The first specifies an offset
from the current record ( so -1 is the record before it, and 1 is the
record after it).  the second argument is the field index, just as is used
with the '%<int>' notation.

	in essence the %<n>  is just a shorthand for (fld 0 <n>) in
the new version of db.

	There are still some things to be worked out (e.g. when to
recalculate these values) this is on the table, but not fully implemented.

Subject: [pilot-db-list] calculated field

Can anyone explain how the calculated field works.
It was my hope that it would allow adding a field from the previous record with a field in the current record, but that doesn't seem to be the case.
Have I missed something?

Thanks,
Carson
