st: Re: Split a variable that has no markers
I guess I fixed my own problem. I discovered generate
newvar=substr(Original,1,1) -which gives me either 9 or 1, then replace
newvar=(Original,1,2) if newvar==1 to get 15 instead of 1. From then on I
can do a similar procedure to extract the rest of the subvariables.
