Did you attach the -label- to any variable in the upper example? In the
lower one, I can see you did...
Note the difference:
*************
vers 10.1
clear*
set obs 10
gen x=1
la def mylabel 1 Phys 2 Role
la list mylabel
la val x mylabel
ta x
save myfile, replace
u myfile
la list mylabel
*vs:
vers 10.1
clear*
set obs 10
gen x=1
la def mylabel 1 Phys 2 Role
la list mylabel
save myfile, replace
u myfile
la list mylabel

Betreff: st: value labels dropped unexpectedly
Sometimes, when I save a dataset in a temporary file and then immediately
reload it, my value label disappears. Can anyone explain why?
This does not always happen; in a toy dataset (below the first example) the
value label is not dropped.
(I am using Stata 10.1.)
