It really depends where you want to take this exercise next, but here is a
shot at the prob:

*************
clear*

inp id x
1  4
2  6
3  7
end

expand 3

bys id: g str1 y="a"
by id: replace y="b" if _n==2
by id: replace y="c" if _n==3
by id : egen float z = seq(), from(1) to(3) block(1)

l, noo sepby(id)
*************

Betreff: st: How to add the same block of data to every individual

Dear All:

Suppose I have the following data set:

id          x
1           4
2           6
3           7
..................

and a "data block" as follows:

y           z
a           7
b           8
c           9

Do you know how I can add this data block to every individual in the
idividial data set. After adding, the new data set will look like the
following:

id     x    y           z
1     4     a           7
1     4     b           8
1     4     c           9
2     6     a           7
2     6     b           8
2     6     c           9
----------------------------

Many thanks!
