I tried this code and it seemed to work:

reshape wide var3, i(var1) j(var2) string

Here is the result set:
var1	var3abc	var3dce	var3kdje
1	99		812		282
2	33		221		772


However, you will have to figure out a loop that will go through and
rename the variables (that will strip out the var3 part of the name and
leave the remaining)

This might actually be a very simple question but I still couldn't
figure out after I tried the reference and the Statalist archive.  I
have a dataset that looks like this:

ID        v2           v3
1         abc         99
1         dce         812
1         kdje        282
2         abc         33
2         dce         221
2         kdje        772
....


And I am trying to change it into this format:

ID       abc         dce          kdje
1        99           812          282
2        33           221          772
....

There are over 1000 variables for each ID (those like abc, dce, kdje
in the example above), and I would really like to keep the original
variable names.  I also tried -xpose-, but then the variable names
(like abc, dce, kdje) became missing in the new dataset.  Is there a
quick way to do this?

Thanks very much for your help!
