Actually the TC version of the 'INPUT-OUTPUT SECTION' conforms to the
COBOL 85 standard, which is as follows.
[ INPUT-OUTPUT SECTION. FILE-CONTROL. {file-control-entry} ...]
Meaning that the 'INPUT-OUTPUT SECTION' is optional, but if present it
must contain a 'FILE-CONTROL' clause and at least one or more
'file-control-entries'.

Yes, that is a know bug.

The specification may have changed for the COBOL 2002 standard or maybe
added an extention.
