I would probably create a new field with either DDS or SQL, populate it with data on “old” field, then delete the old field.
Depending on requirement, creating a LF or SQL view might also work, although this doesn’t actually change the PF

Changing the name of a field is not very different from creating a new file. I would probably use CREATE TABLE … AS … WITH DATA. I don’t know that using CHGPF has any way to retain data from the renamed field. — Tom

Sure, this might be a homework or Inverview question but it might not…

Warning this may have an adverse impact on existing programs, queries and other uses for this file.

1. Change the “DDS” source

2. Use the CHGPF prompt it and identify source – this command will change the file and logicals that use the file format

or

Use the SQL Alter Table Command
