Re: Specify null parameter for SQL UDF

["Peter Dow (ML)" <maillist@xxxxxxxxxxxxxxx>]

Thanks - those are good links.  Looks like they forgot to put it in the 
.empircally for "iSeriesDB2 Universal Database for iSeries SQL 
Reference" for v5r3.  I've been using the .pdf because getting to the 
info center can be difficult sometimes, but I may have to make the effort.

I also notice that in the SCRATCHPAD example, they don't use the *STATIC 
keyword on their local variables, which implies what I was seeing in 
debug -- that the procedure is called with new storage each time.

Thanks again!
