st: stacking unique values of several variables under one new variable

[James Bernard <jamesstatalist@gmail.com>]

Dear all,

I have been struggling with the following. I would appreciate you help

I have a variable ("Technology) that indicates type(s) of a technology
for each record. I want to aggregate the unique values of this
variable under one new variable, say, called "Type:


Technology
-------------------------
Monoclonals
Vaccines
Adjuvant, Vaccine
Combinchem, Monoclonals





Now, i want to create a variable that stores unique values:

Type
-----------
Monoclonals
Vaccines
Adjuvant,
Combinchem

I would appreciate your help.

Thanks,
James
