Or are you handling diverging lengths like in SAP F/G? No, I haven't done that yet. I may give that a try too. I hope it's not too tricky to implement.

The reason we didn't already have that kludge was that 125 is the core max anyway so bumping to MIN(125, 3*125) would be a no-op. Got it. Thanks. Lei
