Answer / naru
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).
