AW: Logical file keyed by active RRN






Hi David,

it's not possible to create a logical file over the relative record no and
eliminating the deleted records.
It's even not possible to create a SQL index over the relative record no.

The only way would be to reorganize your files.

Betreff: Logical file keyed by active RRN


I want to create a logical file where the key is RRN.  I only want
active records listed in this logical.



The goal here is to be able to SETLL by key of RRN and have the pointer
positioned either at the next record in the file or EOF.



This is for a situation where there could be millions of deleted records
in the file.  Doing a regular SETLL by RRN and a READ could end up
scanning thru millions of deleted records.



Doing a SETLL on a logical file _keyed_ by RRN might do the trick.



Any thoughts??
