You'll have to be more precise as to what you mean by that.

Sure, nor problem, below there is a hypothetical example:
Assume that the annual time series A has the values 1, 2, NC, and 4 for the years 1987 to 1990 and that the annual series B has the values NA, 6, 7, and 8 for the same period.

I would like to have a function (or find any way) which would return the series 1, 2, 7 and 4. > series B overlaid with series A
I would be desirable that the solution works both ways to return the series 1, 6, 7 and 8. > series A overlaid with series B

Many thanks in advance, k

You can use the @recode function for this:

Code: Select all

series c = @recode(a=na,b,a)

or

Code: Select all

series c = @recode(b=na,a,b)

works perfectly, many thanks
