st: Replacing the value of a variable

[oezguer.guererk@uni-erfurt.de]

Hello,

for each given "subject" and for all 20 "period"s associated with the 
respective subject- I would like to fill the variable called "firstcon" 
 with the value of another variable "con" from "period" 1 of the 
respective subject.

For example: if subject 3's "con" variable in "period" 1 is "17" then 
this subject's "firstcon" variable should be filled with "17", for all 
periods from 1 to 20, i.e., for all 20 rows.

How can I do this? Thank you very much for your help!
Ozgur
