Set Expression Clarification

[#1]

How's everyone doing?

Can someone help me clarify the difference between the following set expression? The goal is to return last 7 days [DaySeqNum] between max([DaySeqNum]-7 and max(DaySeqNum)

[DaySeqNum]= {">$(=max([DaySeqNum])-7)<=$(=max([DaySeqNum]))" }

Correct Result (20110125 to 20110131 assuming max([DaySeqNum])=20110131)

[DaySeqNum]= {">=$(=max([DaySeqNum])-7)<=$(=max([DaySeqNum]))" }

Incorrect Result (20110124 to 20110131 assuming max([DaySeqNum])=20110131)

The only different is >= versus > right after the first quote. Why wouldn't >= work? Shouldn't it return [DaySeqNum]-7?

If there are qvw examples of set expressions filtering on date ranges, please forward them if possible.

Your help is much appreciated!
