Hi Networkers,
	
	
	Another question about OS/2, HPFS and the OS/2 calls to file function.
In my previous message, I told that I couldn't access a file on an HPFS disk
with the C/2 open and fopen functions. So, I used the OS/2 call DosOpen.
And then, suprise. I thought HPFS could handle long file name... So, I tried
to DosOpen the file ROUTETABLE.DATA, but it fails, returning me the error
206 (FILENAME_EXCED_RANGE). So, I had to reduce it to ROUTE.TAB, without 
changing anything else... and it works ! But my manual tells me that :
'the High Performance File System (HPFS) permits having many parts in a name 
if each part is separated by a period.' and 'Generally, long file names support
255 characters per name part; the HPFS names support 254.' [from IBM 
Operating System Extended Edition Version 1.2 User's Guide Volume 1: Base
Operating System]

	My question is : WHY ? Why can't I access a file that is fully 
supported by the file system ?

	Paul.
