Length for database record-item "!AF" must be greater than zero

  Explanation:  The minimum size for a COBOL data item is 1 byte.  In
  a DBMS Data Description entry, the minimum size for a subschema data
  item is 0 bytes.  The compiler treats the record-item as if it has
  a length of 1 byte, which may produce run-time errors.

  User Action:  You must take one of the following actions:

    a. Redefine the subschema data item to be at least 1 byte, and
       recompile the subschema with the DDL Utility

    b. Do not use this subschema with VSI COBOL
