Write an Ether program and run it. The output shows what the program printed with debug and the values it left, top first. Choose written in Ether to run it on the 51 kernel words, with the rest of the language loaded from its Ether definitions.

<< Words that are not defined are pushed; debug prints the top value. >>
" Hello, world! " debug

{ dup # 2 swap less-than
  { del # 1 }
  { dup -- factorial * }
  either } => factorial

[ # 1 # 2 # 3 # 4 # 5 # 6 ] { factorial } map debug

Hello, world!
( 1 2 6 24 120 720 )
values: ( )
