Well, Stata never promised to -display- in blue, did it? [P] display
enumerates the colors on the standard background. If one really wanted blue,
one would have to right-click the results window and change stuff on the
"Results color" tab...

Betreff: Re: AW: st: AW: compare files, vars only
Steve's example can be made more instructive by adding a -drop-
command after -sysuse auto, clear-.
clear*
sysuse auto, clear
drop gear_ratio displacement
save newauto, replace
sysuse auto, clear
drop mpg
qui ds
loc first `r(varlist)'
des using newauto, varlist
loc second `r(varlist)'
loc diff12 : list first - second
loc diff21 : list second - first
di in red "In 1st, not 2nd: `diff12'"
di in blue "In 2nd, not 1st: `diff21'"
The last two lines return this output:
In 1st, not 2nd: displacement gear_ratio
In 2nd, not 1st: mpg
Incidentally, the "blue" output is written in green to my screen. I use
Windows.
