Subject   st: Replacing observations with values from other observations

Hello everyone,

I would like to replace specific observations with values from other observations. I can use 

replace var1 = 500 if obsID==5

to replace the value for variable 1 in the observation with ID number 5, with the quantity 500. What I would like is code that allows me to make a reference to another observation, in place of that "500." Does anyone have a way to do this? (My option of last resort is to do this in Excel, but I would prefer to keep working in Stata.)

Thanks in advance for any help you can give,
Moses
