SUMMARY
If you define a function macro where one of the arguments expected is a reference (TYPE 8), the function macro acts like a volatile function. This means that if you turn on automatic calculation, the function recalculates whenever you make a change to any cell in an open document.

You can avoid this problem by turning on manual calculation or by changing the argument to another type. For example, if the reference is to a range of cells, the argument could be changed to expect an array (TYPE 64). This works as long as the range is less than the maximum size of an array (approximately 6400 cells for Microsoft Excel for the Macintosh version 3.0 and 1600 cells for Excel 2.2).
