Hi,

 may be my Enigma hacking has encyphered my brain also...but...

 What is wrong with this code:

 etwdata=[[1,2],[3,4],[5,6]]         # only example data

 etwdata.each{ |rot|
 rot.each{ |val|
   print (val + ?A).chr," "          # here ruby fails...error message below...
 }
 print "\n" 

 Ruby's error message:

 basicenigma4.rb:175: warning: don't put space before argument parentheses


 Sorry... but _I_ dont see anything wrong here...

 Ruby.use!
