unrelated to your question: the cum() function may be helpful here > > I would like to add the series $i_p and $i_m to the current variables > but I cannot find out how to use the "return" command correctly in this > context. Does anybody have a suggestion? If the number of returned series is known in advance and small, you might also try the pointer variant: function void getoutput(series *out1, series *out2) ... end function series output1=0 series output2=0 getoutput(&output1, &output2) The advantage is that the names of the returned series are controlled not by the function code, but by the calling code.
