Correct about my typo. The example is also irrelevant, because of the

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'
}
