RE: Creating a SQL UDF

Thanks Scott.

That did it.  I was so focused on a deeper problem that I overlooked the
obvious.

My next guess would be that your parameters don't match, and so you are
corrupting memory.  Looking back, I see that your RPG code returns a
65535A, which is larger than SQL could support.  Your latest SQL is only
reserving memory for VARCHAR(1000).  That means that your RPG will
overwrite 64535 bytes of memory that haven't been reserved to it -- and
that can cause just about any sort of error.

Please make your parameters match.
