RE: User Space or Data Queue or PF or IFS

["John Brandt Sr." <pgmr@xxxxxxxxxxxxxxx>]

Rick,
It is pure ASCII data in a single stream. 
There are no end-of-record indicators, 
nor end of file. When the data ends, it ends.
I have to read/parse and convert it on the fly,
thus the original method of using User Space.

John,

Could you provide a little more information please?  Where is the data
eventually going to reside?  What type of data is being read (comma
delimited, fixed length, ...)?

The data queue option will also have a size limitation (can't remember it
off the cuff) so I'm not sure that will resolve a size issue.  If entries
can be removed as soon as they are placed onto the queue it may not be an
issue.

I'm a little confused about why the record calculation if using a data queue
wouldn't work for other methods also.

Rick
