RE: User Space or Data Queue or PF or IFS

["Chevalier, Rick" <Rick.Chevalier@xxxxxxxxxxxxxxx>]

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
