[Info-vax] ODS-1 Index File extension headers

[Lee Gleason]

  I've been doing a little experimenting with ODS-1 disk structures lately, 
specifically working with the Index File.

  Does anyone know, under what circumstances the Index File gets an 
extension header? Does it ever happen at any time  other than  INIT time, or 
when the HOM command is used to change MXF?

  Can the Index File ever have more than two extension headers, and are they 
ever not headers 6 and 7?

  Thanks
