This is a large area. Two suggestions only:
I like using -assert- to assert what should be true.
You can -capture- its result and -list- conditional
on there being a problem.
capture assert sex == 0 | sex == 1
if _rc {
list sex if !(sex == 0 | sex == 1)
}
Alternatively, tag problems and save the -list-
until later.
gen problem = <x1 shows problem 1>
replace problem = problem | <x1 shows problem 2>
.
.
.
list if problem
