To all,

Can anyone tell me exactly why this sysstat & 0xf = 4 is used and what
exactly it means etc, I know that sysstat is a field in the sysobjects
table but the & 0xf = 4 is the bit thats confusing me.  Please ignore my
ignorance if this is simple as we are working on a new technology for
our stocktaking along with another company, and they have used this is
some code to create an SP on the fly:

IF EXISTS (select * from sysobjects where id = object_id('dbo.mySP') and
sysstat & 0xf = 4)  drop procedure dbo.mySP

Thank you for any help on this in advance....
