A 6-column by 50-row range (a1:f50) is filled with random numbers. The
numbers are from 1 to, say, 100.

What Excel function, written in a serarate cell, will return the cell
location of the first occurence of a given number as we read the cells
from left to right and from top to bottom in the range?

(e.g., "73" occurs in cells D32, A56, B88 and F97. D32 would be the
'earliest occurence'. What operator, function or formula would report
back "D32"?)

From a college class a long time ago, I seem to recall another kind of
spreadsheet that could do that.
