One of the objections raised against the adoption of the Cobol 85
standard was that it might invalidate code that had been lost and then
found after the standard was published.

Does this mean the same objection might be raised against the next
release of the Cobol standard :-(

[Probably, by people whose management know nothing about software and
insist that they only use the current compiler. The various revisions
of Cobol have deliberately been slightly incompatible, pruning out
crud from the '60s, and of course compiler vendors still support the
old lanauges. -John]
