Answer / sree
There are3 level identifiers for any PF. They are
1. At File level
2. At Member level
3. At Record level
Say PF1 is having two members MBR1 and MBR2. So, There will
be 5 level identifiers. 1 for PF1, 1 for MBR1, 1 for MBR2
and 1 for RecordFormat(MBR1) and 1 for RecordFormat(MBR2).
When you made changes to RecordFormat of MBR1, then only
Level identifiers of RecordFormat(MBR1) and MBR1 will be
changed.
