<pre>Normally (...) for user defined functions that are invoked as spreadsheet
functions, yes.
Now it gets complicated: for whatever reason (I don't know the history behind
that specific VBA implementation) if there is
Option VBASupport 1
which here is the case then a XCellRange object is passed for cell references.
That indeed allows BASIC to modify the cell. It should not and can result in
undesired side effects, like here even Err:522 circular references being
detected because the cell value modified triggers another recalc that runs into
a currently being calculated cell.
Changing stableford() to not modify its score argument gets rid of all side
effects.</pre>
