Hi Eike, all,
I have been concentrating on converting IFS functions to their
equivalent with nested IF functions, e.g. IFS(b1;r1;b2;r2) to
I now think I know where to insert ocIf tokens in the IFS-function
string when looking at FormulaCompiler::Factor(), but I don't know how
to insert a FormulaTokenRef in the code and not destroy the stack, jump
array or other at the same time.
For some time thought that FormulaTokenArray::RewriteMissing(...) might
be a better and easier place, but this function is only called after
ScInterpreter::Interpret(), so that has no use.
Do you have any suggestions where and how I might try to insert these
extra ocIf, ocSep and #NA tokens (and replace ocIfs with ocIf).
With ocSwitch I also must be able to copy (the result of) the first
argument on top of the stack before the next ocIf is executed. The
equivalent in those case would be SWITCH(x;b1;r1;b2;r2) converted to
