Will do nothing. Can you read cannot read deleted records. I assume DELETION is a physical deletion not a logical one.

RECFM=FBA

If given in jcl, will cause 1byte carriage return control character to be written in first byte of the data record. Actual data will start from 2nd position onwards.

Hello,

Are you sure you have quoted the interview question correctly?

Programs do not "have indexes"; tables have indexes. If you have a performance issue due to indexes it may be the insert/delete (or certain types of select) that are affected. Insert and delete must create and remove all of the index entries for that row.
