Data _null_,

No, I thought I might as well have just waited for you. I liked your structure better with no DO-block, so that bothered me.

I have the DEFINEDATA function because I copied code without much thought since I don't work hard enough. (I doubt if DEFINEDATA added that much time to the run.) That also explains my H's.

Perhaps including the HASHEXP: parameter would have been helpful for more realistic situations, but Paul's data didn't seem to require it.

You might think I copied your program. I did not. Interesting we both chose H1 and H2 as names for the hashes.

We did, I believe, each of us include an unnecessary bit.

I include, hash(ordered:'a') which has no effect. You include, defineData() which while doing no harm has no benefit that I can see.
