[Info-vax] Empty blocks in FILES-11 directory files.

[Volker Halle]

Additions:

When compressing a directory file, EFBLK will be updated, but the blocks between EFBLK+1 and the highest block allocated will  not be overwritten with zeroes, even if 'file high-water marking' is set.

$ CREATE/DIR/ALLOC=nnn will create .DIR file with zeroed blocks after EFBLK (if 'file high-water marking' is set).

Mark, what is your definition of 'empty blocks' - all zeroes ?

Volker.
