Re: Passing XML back and forth with RPG and .NET

[Alan Campin <alan0307d@xxxxxxxxx>]

Use the temp IFS. Scott's EXPAT parser will read directly from an IFS table
and they are very fast. Writing to a physical file is slow. There should be
nothing to writing to the IFS. I have a service program that wrappers
everything that I use. The parsing back would be handled by EXPAT.

You could also pass a 64k varchar but like you said it might be too big.
V6R1 has much bigger limits.
