You need to make your "V*" lowercase "v*" in your example because v1,
v2, v3 are lowercase (in original do-file, my V's were uppercase)
clear
set obs 1
*obs was 0, now 1
gen v1 = 1
gen v2 = 2
gen v3 = 3
foreach x in v* {
d `x'
}

Well, it does not work for me. (I do know what a wildcard like V*
means
in Stata. The point is that you need -of var- to make explicit that
you
have one.)
. clear
. set obs 1
obs was 0, now 1
. gen v1 = 1
. gen v2 = 2
. gen v3 = 3
. foreach v in V* {
2. d `v'
3. }
variable V* not found
r(111);

I have various comments on this code.
1. -foreach x in V*- won't work. Eric is probably thinking of
-foreach x of var V*- but in this case -foreach v in V1 V2 V3- takes
no more thought.
-foreach x in V*- works for fine for me. It loops over all the
variables V1-V3.
