Here’s a really weird #uxn “Hello World” program:

    ( hello.tal )
    ( devices )
    |10 @Console [ &vector $2 &read $1 &pad $5 &write $1 &error $1 ]
    
    ( macros )
    ( print a character to standard output )
    %EMIT { .Console/write DEO } ( character -- )
    %EMITK { .Console/write DEOk } ( character -- character Consolewrite )
    ( print a newline )
    %NL { #0a EMIT } ( -- )
    
    ( main program )
    |0100 #0a6f
          #6c
          #6568 
          EMITK NIP DEOk NIP DEOk DEOk NIP DEOk NIP DEO
          ,wo LDRk ( wo w -- )
          STH #0d SUB STHr
    @looper #00 POP ( wo w -- )
          EMIT ( wo -- )
          INC ( wo+1 -- )
          LDRk ( wo+1 o -- )
          DUP #00 NEQ ,looper ( wo+1 o 1 looper -- ) 
          JCN ( wo+1 o -- )
          BRK
    @wo
