Hey Chris, I got a problem when I run the data process. When I set two or more data together, if they have variable that have same variable name but different variable length, the generated variable's length will be aligned to the shorter one. This also happens even when I pre-format the short one to be the same format. I have no idea how to deal with this situation. I notice that there 3 attributes for each variable: Len, Dlen, Format. What's the difference of them? How set these attributes? Thanks!
