Why *MAP and * DROP?
When we copy data from FILE A to FILE B and if FILE A has
20 fields and FILE B has 30 fields (say there are 10 fields
which is not common among both the files). Using *MAP and
*DROP option we can copy the data from FILE A to FILE B.
All the fields would be mapped between both the files and
the unmatched fields would be dropped.

Which command uses *MAP & *DROP - CPYF command (Copy file).

Answer / panduranga nayak

The keywords *MAP and *Drop is used by the IBM command CPYF.
This keywords are used to MAP the column or drop the column
whenever a field added/Deleted from a physical file.

Answer / manoj

*MAP will check byte by byte.
When we copy the records from one file to other file then
we used CPYF command.

Answer / samba
