PREIMAGE Tables in FairCom DB SQL

A performance gain can be obtained in some situations by avoiding transaction logging of files, thereby foregoing the protection of recovery. With FairCom DB ISAM it is possible to create files with such a transaction mode using ctPREIMG as the file mode. This support is now extended to FairCom DB SQL Tables as an option when they are created. The additional option, 'PREIMG', has been added to the FairCom DB SQL keyword STORAGE_ATTRIBUTES.
