Hi all,

I'm new to the list.  Can anyone direct me to an efficient, preferrably
already existing way to get the unique values of a categorical variable into
a macro.  The goal is just like creating a "by", but I need to have the
unique values list.  Let's say I can get the unique values in the macro

I then want to be able to loop over all unique values in the list

Foreach uniqval of local `uniqlist' {
  execute code
