Do the multi format logical file need to have same key field attributes for each record format? what is the significance of K *None in such Logical files?

Usually we specify *none as a key field to avoid unwanted key comparisons between key fields in the record formats of MFLF
Reason to avoid comparison are 1) the key fields should be different attribute
2) we do not want the sequence the records on the particular key filed
