The code that found a nearby data target for an instruction operand was searching backward but not forward. We now take one step forward, so that "LDA TABLE-1,Y" fills in automatically. This altered 2008-address-changes, which had just this situation. It didn't alter 2010-target-adjustment, but the existing tests were insufficient and have been improved.
