ARC/INFO regards a Grid as having intrinsically square cells, so as
you state it, you can't do it. A possible work-round:
Use the Net sub command of the Generate command to create an array of
rectangular polygons. Create an numeric attribute whose numbering
corresponds to the order of your data, then use the joinitem or relate
commands to bring your values into the coverage.
