Dan,

I would create a working storage data structure to hold the record
contenct (use the copy dds command and prefix WS- perhaps) and then use
the READ file-name INTO ws- data structure, delete the record just read,
change the key fields, then WRITE record-name FROM ws- data structure. 
This way you won't lose the information.

I wish IBM would give us a way to update the keys without having to delete
first.  The OPM had FS21DUPKEY (If I remember correctly) that would allow
for  key changes.  ILE does not.  You might want to post your question or
comments on the COBOL list.
