Martin,
Is that the result of the second loop? Or the first??

Sure all those single quotes transferred correctly? Some email programs kill
them, so you should also try to obtain the code from the archive.

Hm... I tried this and the second loop merely erased the labels on the a`i'
vars. What'd I miss??
clear*
. set obs 1
obs was 0, now 1
. forv i=1/10{
2. gen byte a`i'=1
3. la var a`i' "abs(x`i')"
4. gen byte x`i'=1
5. la var x`i' "HeadGy"
6. }

Very true, and I realized it the moment I hit the "send" button. So go ahead
and do this manually:
*************
clear*
set obs 1
forv i=1/10{
gen byte a`i' =1
la var a`i' "abs(x`i')"
gen byte x`i'=1
la var x`i' "HeadGy"
}
d
//transfer
forv i=1/10{
la var a`i' "`=subinstr("`:var la a`i''", "x`i'","`:var la x`i''"
,.)'"
}
d
*************

Indeed, copydesc is an oldie. But clonevar clones the entire variable,
including the contents. So using clonevar here would copy over the variable
labels "as-is," without the modification that I desire, and it would also
copy over the CONTENTS of the oldvar to the newvar.
I'm just looking to copy the label from a list of oldvars to a list of
newvars, but also want to add some text to those labels.

-ssc d copydesc- looks like old code to me, although it may well serve a
useful purpose, and only got like 35 hits last month. It is # 66 on Nick`s
hit list (-ssc hot, auth(cox) n(66)-), but no discussion related to it has
been recorded in the archive since the end of 2003. That could be because
official -clonevar- can do its job more efficiently. Since Nick is the
author of the official command as well, there might be a connection there...

Betreff: st: copydesc with a twist??
I'm looking for a quick way to copy variable labels from a set of variables
(ex. x1-x100) to a set of new variables (ex. a1-a100), but I need a minor
modification of the new labels.
Nicholas' copydesc command comes very close, as I can imbed it in a loop as:
For J in num 1/100: copydesk xJ aJ
But here's the rub. In this case all of the aJ variables are a
transformation of xJ. I'd like the transformation to become part of the
variable label too.
Here are two variables as a specific example:
storage display value
variable name type format label variable label
----------------------------------------------------------------
x2 float %8.0g HeadGy
a2 float %9.0g abs(x2)
I would LIKE the label for a2 to be "abs(HeadGy)" not "abs(x2)". I have a
zillion of these, so I don't want to hand-code them all...
Anyone know of an ado already written to do this? Or a way to use
copydesc??
Much appreciated,
Rob
