Relative spreadsheet reference (source code)

= Relative spreadsheet reference

A <relative spreadsheet reference>, such as `A2`, allows both coordinates to change when its <spreadsheet formula> is copied. From `C2`, `A2` means two columns left, in the same row. Copy `=A2*B2` from `C2` to `C4`: the displacement is zero columns and two rows, so it becomes `=A4*B4`. The row number changes to retain the same positional relationship to the <spreadsheet formula>.
