Hello, I am working on SAS Code that will allow me to de-range a data set. I need to create a list that has the mapping from var1 to var2. I have done some set up work and I now have a data set that looks like this:   var1:   var2 (character): a          305 a          306-308 b          400 b          401-405   what I need is an output that looks like this   var1:   var2: a          305 a          306 a          307 a          308 b          400 b          401 b          402 b          403 b          404 b          405....   Hopefully this makes sense!     ...
