Will the binder so "copy" members that checksums can be recreated? If not, I consider the operation to have some of the character of a recompilation reather than a "copy". And is there any way to verify that the metadata resulting from a "copy" by the binder are identical?
In the open world, suppliers regularly (though not always) supply checksums that recipients can verify. SMP/E network installation verifies checksums over part of the process (though far from end-to-end). -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
