If the SAME RECORD AREA clause is specified for several files, the record
description entries or the file description entries for these files must not include the
GLOBAL clause.

A data-name described using a GLOBAL clause is a global name. All data-names
subordinate to a global name are global names. All condition-names associated
with a global name are global names.

If the GLOBAL clause is used in a data description entry that contains the
REDEFINES clause, the global attribute applies only to the subject of the
REDEFINES clause.
Example 2-2 contains an example of the use of the GLOBAL clause.
