Dear Statlisters,

I am searching for something that would do the equivalent of an 
'ereplace'.  I have a set variables for which I generated a -rowtotal- 
given some condition, e.g. (egen x=rowtotal (d1-d40) if y=1), but then 
I need to replace some values in that same variable (x) with a 
different -rowtotal- given a different condition.  I dont know how else 
to explain it except to say that if there were an  'ereplace' command 
the next command would look like this:

"ereplace" x=rowtotal(d2-d40) if y=2

In other words, I need to replace values in x with different sums of 
variables.  I need to do this for a great many conditions so typing out 
the list of variables to be added for each condition would be a minor 
pain.
