Re: Multiformat Logical File

Or, would it be like IP and IS with matching records defined?  Lots less
coding.

Satheesh -
 
Suppose that you have a Sales order detail file that has currently active
sales order information, and a history file with the same record layout
containing archived sales order information.
 
You can build a keyed multiformat logical over the two files to use in an
RPG program, and by using SETLL and READ or READE on the FILE name, not the
record format name(s), you can process the current and historical
information through the use of the logical file.
 
This is functionally equivalent to performing a UNION of the two files to
get information via SQL.
 
Another use for multiformat logicals is with traditional AS/400 - iSeries
EDI packages.
 
Depending on the complexity of the EDI document, you will have a Header file
and one or more Detail files that are used to construct the data that drives
the EDI translator.  You will typically tie all of these files together with
a multiformat logical file and use the logical file in the EDI translation
process.
