Since we can't put a link statement and program on a single line, we implement a simplified inline sprintf so we don't have to deal with all the double quotes or substrings and offsets. If we'd needed to write multiple procedures on a line it can be done [[Icon%2BUnicon/Intro#Semi-colons| Semi-colons in the language intro]]
<langsyntaxhighlight Iconlang="icon">procedure main();yes:="Accept";no:="Reject";pat:="procedure main();yes:=$;no:=$;pat:=$;a:=[yes,no,pat];narc:=char(0)[0:0];pat?{while narc||:=tab(find(char(36))) do{narc||:=image(get(a));move(1)};narc||:=tab(0)};write(if read()==narc then yes else no);end";a:=[yes,no,pat];narc:=char(0)[0:0];pat?{while narc||:=tab(find(char(36))) do{narc||:=image(get(a));move(1)};narc||:=tab(0)};write(if read()==narc then yes else no);end</langsyntaxhighlight>

Program written on a single line to avoid problems with indentation. But we wanted to avoid the too easy solution consisting to read the source file. Input should be terminated by an end of file (Ctrl-D on Linux).

For the narcissist to work you must be very careful with whitespace. The following version works if it is given to standard input as exactly one line terminated by a newline character.
 
Note how the code takes advantage of Perl 6's ability to nest quoting delimiters.

<small>Aside: I suppose there should really be a leading <code>without js -- file i/o</code>, but I wanted to keep it a 1-liner.<br>
 
Interpreted-only, as is: to allow a compiled version to run, change <code>command_line()[2]</code> to (say) <code>"test.exw"</code><br>

or maybe <code>substitute(command_line()[2],".exe",".exw")</code>, and ship with/install the source code file.</small>

Sample session:
<pre>
Enter the number of lines to be input followed by those lines:
 
2
import "os" for Process, Platform
import "io" for File, Stdin, Stdout
 
not yet finished
</pre>

<langsyntaxhighlight lang="zkl">stdin:=File.stdin.read();
thisFileSrc:=File(System.argv[1]).read();
println((stdin==thisFileSrc) and "input matches "+System.argv[1] or "No match");</langsyntaxhighlight>
Since zkl is [usually] compile-when-run, we just compare the contents of source file to stdin.
