[Isis-users] How to check for records which has no entry in descriptor field

[Piet De Keyser]

Leyla,

I would take these steps:


  1.  Create a FST for indexing, containing only one line, e.g.

1 0 if a(v76) then MFN fi

This will give you a list of all records numbers with v76 being empty.

  1.  After creating an index file from the whole database with MX and this FST, I woud visualise this index with ifleys and export it to a TXT file, e.g.

Ifkeys test>test.txt

This will give you a list of all records with the empty v76 which you can print. This printed list will make it easier to go over every record with the empty v76.

Dear all,

I am checking certain entries in ABCD and want to find records that have no entries in the descriptor field v76 / (MA_), how do I proceed?

Thank you very much in advance.
With best regards

Leyla
