Yep, think I spaced this whole area as I mentioned in the replay to Dave...

<It reads the entire spooled file until it gets to the "starting page".  It
starts on page 1, them page 2... The spooling process is designed to read/write,
read/write.  Reads are fairly cheap, write are more costly.  Never the less, 
when
bypassing pages, it's not really working like the original design.  So it uses
lots of CPU cycles doing read, compare page #, read, compare page #...  When it
catches up, then everything goes back to normal.>

Gottcha - I knew the "start at page 1 and then page 2, etc" but didn't really
understand or think about the rest and appreciate the info !

<The first note did not provide enough detail.  This could have been a 4MB model
B10.>

Sorry about that - 2179-620 1GB (1012) 20.97 GB DASD...

Thanks !

Chuck
