z/OS FTP Directory Listing - Column “Volume” Valid Values

Question

Besides the volume ID and status "Migrated", what other values might get returned by IBM z/OS MVS FTP server, in column "Volume" (default DATASETMODE directory listing format)?

For example:

Volume Unit    Referred Ext Used Recfm Lrecl BlkSz Dsorg Dsname
Migrated                                                F010317A.FD2F
SS1010 3390   2017/05/31  1    1  FB     309 27810  PS  F010917A.FSSP

Looking at this with an eye toward parsing directory listing results in an FTP client.

Answer 1

It seems column Volume may contain three values, for directory listings produced with default DATASETMODE format:

1. Volume ID
2. Migrated
3. MIGRAT

For example:

  function IsMVSMigrated(const AData : String) : Boolean;
  begin
    Result := TextStartsWith(AData, 'Migrated') or TextStartsWith(AData, 'MIGRAT');  {do not localize}
  end;
