I worked on software at a very large mortgage bank doing parsing of 3270 connections ("green screens") that had several thousand users. We had to rely heavily on field positions using X,Y coordinates.
10/06/03 was when they switched to 10-digit loan numbers from 7-digit ones... Care to guess what happens when you add 3 characters to a screen with 0 room available? More interestingly is what happens when you don't have access to the testing systems before the change goes live.
We got a phone call or two that morning...
