ILE COBOL Programmer's Guide
Pointers can be defined in the File Section, and can be set and used as can
any other Working-Storage pointer data items. There are, however, some
restrictions:
- If a file has blocking in effect, only the first record of a block is
guaranteed to be on a 16-byte boundary. Thus pointers should not be
defined for files with blocking in effect.
-
A record containing pointers can be written to a file; however, on
subsequent reading of that record, the pointer data items and
procedure-pointer data items equal NULL.
