Introduction
(Next) (Previous) (Table-of-Contents)

This document was generated from a COBOL copy file using the SimoTime Record Layout utility program. The primary intent of the following table is to provide additional information about a file record layout using a COBOL Copy File as input. For example, the position of a field within a record is not easily determined from the COBOL Data Structure. Also, the actual physical length for group items, packed fields, binary fields and tables must be calculated manually. This information is provided by the SimoTime COBOL Copy File Analysis program.
