RE: help asked for Calc jump function with empty arguments

Hi Eike,

(To make it clear for me, =IFERROR(1/0,) results in an empty cell in Excel and an error in Calc.)
Popping ocMissing seems a bit of a problem - for me ;-) - as ScInterpreter::Interpret calls 
ScIfError() first and then changes opcode. So, when I detect ocMissing, I don't know from which 
function.
In the case of IFERROR I could use a boolean to return an empty cell, but in the case of IF I need 
to know the result of the expression in the first argument or whether the ocMissing refers to the 
ifTrue argument or the ifFalse argument.
I hope you understand my problem.
