Apologies for previous premature post.
Your punishment is that you got what you asked for!
First time round the loop, you recoded missings in -v2- to 1 if -v1- was
55555 and 0 otherwise.
As this divides up the field exhaustively, that first step means that
there are no longer any missings, so no further changes take place.
Your line
recode v3 (.= 0) if `val' != v1
should be removed or moved.

I am trying to recode a variable (v2 or v3) based on whether the
observation in v1 is present in a list of numbers (a local macro).
Below I've pasted code for my two different approaches, both using -
macro shift-, but neither approach gets past the first item in the
list "55555".
**********
clear
input v1
55555
22222
11111
66666
11111
88888
77778
99999
33333
end
gen v2 = .
tokenize 55555 66666 77777 77778 88888 99999
while "`1'" != "" {
recode v2 (.= 1) if `1' == v1
recode v2 (.= 0) if `1' != v1
macro shift
}
gen v3 = .
local zip 55555 66666 77777 77778 88888 99999
foreach val of local zip {
recode v3 (.= 1) if `val' == v1
recode v3 (.= 0) if `val' != v1
macro shift
}
*********
The resulting dataset looks like:
v1 v2 v3
55555 1 1
22222 0 0
11111 0 0
66666 0 0
11111 0 0
88888 0 0
77778 0 0
99999 0 0
33333 0 0
Thanks for any help!
