HPFS stands for High Performance File System.  It is a replacement
for the FAT system.  Before rev. 1.2, OS/2 had still been using
DOS's file system (FAT).  HPFS looks a lot like FAT but has extended
attributes and extended names.

[CAUTION:  Writer merging with another thread:]

I understand that OS/2 1.2 allows the DosOpen function to specify
additional flags for the fsOpenMode parameter.  This feature is
available only on HPFS partitions.  These new flags are advisory -
they inform the operating system of the programs intent.  They advise
the file system of whether the program will access a file randomly or
sequentially, for example.  This allows the cache system to make
informed decisions - extending the efficiency of HPFS.  I'm missing
FAT already.

I suppose if you knew (I don't) what the values of these manifest
constants were, a programmer could write code for it now.  The next
OS/2 Softset should have these goodies, in any case.
