Re: Stored Procedures

The slick thing too is that you can map the array to a user space so you can
return up to 16mb of data with your array without taking a bunch of storage
in your program and worrying about making the array big enough. Have tested
it and it does work. Oh when, oh when is IBM going to give use terabyte User
Spaces and eliminate the 16mb limit?
