I'm no Steve Wampler, but I had a go at option (c), the loosest.
set difference does the work.
procedure main(a)
thechars := cset(a[1]) | stop("No characters found; the word \"\"
is made of no characters")
thewords := open(a[2],'r') | stop("No words to test. Is the file
valid?")
every aword := !thewords do {
charsofaword := cset(aword)
if (*(charsofaword -- thechars) = 0) then write(aword)
}
end
