Yes, sir. Exactly. Thanks. I'll play around with what you've given me here when I'm back at it tomorrow.

I want to simply keep that description, which I thought was called the variable label. >> >> From my own file: I have variables called campus08 campus09 campus10. The description for these variables is the same in all three years (the two-digit number after the variable stub): "Campus ID Where Student Attended School." When I reshape from wide to long, I now have one variable, campus, that has no description. How can I keep the label "Campus ID Where Student Attended School"? >> >> Thanks, >> >> >> ---------------------------------------- >>> Date: Wed, 19 Dec 2012 21:24:41 -0500 >>> Subject: Re: st: Preserve Variable Labels After Reshape >>> From: joerg.luedicke@gmail.com >>> To: statalist@hsphsun2.harvard.edu >>> >>> Say we have 2 observations and 2 variables in wide format which we >>> would like to reshape long. >>> >>> The data in wide format would look like: >>> >>> clear >>> set obs 2 >>> gen id=_n >>> forval i=1/2 { >>> gen x`i'=`i' >>> label var x`i' "label `i'" >>> } >>> >>> . li >>> >>> +--------------+ >>> | id x1 x2 | >>> |--------------| >>> 1. | 1 1 2 | >>> 2. | 2 1 2 | >>> +--------------+ >>> >>> Both variables x1 and x2 are labeled.

The labels are the same. I am simple trying to keep those labels after a reshape.
