Bingo! That got it, John.

I sure can't figure out why I reported it working yesterday, after he
added his header checks. And I could've sworn I used
it on some posts - not just testing it - later.

Is this all because I just turned 60? :)

Here's the version for slang v1.

#v+
%

define whois_postinghost () {

variable status= is_article_visible ();

if ( status & 1) {
variable postinghost= extract_article_header ( "NNTP-Posting-Host");

variable ph_exists= strlen ( postinghost);

if ( ph_exists > 0) {
() = system ( "whois "+postinghost+" | less");
} else {
error ("This article doesn't contain a NNTP-Posting-Host header");
}

} else {
error ("You need to display the article to check");
}

}

definekey ( "whois_postinghost", "\eH", "article");
#v-

I hope those delimiters work; I've never tried using them before, and I
hope the characters I *see* in Troy's posts are what one actually enters
when trying to delimit code.

I wonder why in the first-line comment it's not referred to as
.
