  Hi! there is a matrix

   matrix : array[17,array[17,int]]
  Run

  There's a code that displays a picture

   draw =
      for y in matrix:
          for x in y:
              if(x==1): echo("#") else: echo(" ")
  Run

  output must be like

    #####
     #            #
     #   #   # #
     #            #
     #  ###  #
      #####
  Run

  Echo works correctly in this case - in your case it doesn't work the way you want because you don't need newlines in rows. Your code should be something like this:

  proc draw =
      for y in matrix:
          for x in y:
              stdout.write if x==1: "#" else: " "
          echo "" # newline
  Run

  echo adds a new line, use stdout.write() instead
