Hi, I'm trying to use proc similarity (hope someone is familiar with it) and it needs sequential column variables, eg. Var1 Var2, Var3, ... Var1000, but when I sort it, it sorts as Var1, Var10, Var100, Var101, Var2, ... Var999... How can I keep the normal numbering system 1,2,3,...1000 .. If anyone knows proc similarity, I have 2 groupings that would duplicate the Date which is the ID variable. I'm trying to use a by statement in proc similarity but I'm getting an error that the ID (date) is duplicated from all these groups. Any suggestions, thanks.
