Thanks! As is obvious, I am pretty unfamiliar with spreadsheets. I think this is just what I want to do. If I'm understanding correctly, the cell offset in the original formula becomes the column offset and all cells in the offset column are calculated accordingly because the logical and numerical relationships between cells as defined in the formula, would be repeated in each row.
I think you are exactly right. On the chance I'm misunderstanding you, I'll say it in my own words.
If I'm typing a formula in a cell, I might type the coordinates of a referenced cell like "C2" (column "C", row 2). But, it doesn't get recorded like that internally. If you're typing that into a call at "E7", it gets recorded as offsets: -2 horizontal and -5 vertical. So, if you copy and paste the E7 cell, the offsets are copied. So final destination of the paste will not reference "C2", but some other cell. So, if you paste into cell "F20", the referenced cell would be "D15".
original E7 references C2
pasted F20 references D15
You can change the C2 reference to be absolute in either or both dimensions. If you are editing the formula in cell E7, you'll see a down-arrow on C2. In the popup that it gives you, you can select "Preserve Row" and "Preserve Column". That means "Preserve when copying". For example, if you only select "Preserve Row", then:
original E7 references C$2 (The $ is used to indicate an absolute reference in the vertical dimension.)
pasted F20 references D$2
