While I have not exhaustively searched Help/Documentation Center for an answer to my question, I have put forth a yeoman's effort without any success.

Does anyone know if it is possible to suppress Out= on an on-going basis within a notebook without also suppressing In:= and if it is, could you please tell me how?

Welcome to Mathematica.SE! Instead of signing the post, please set a display name. user12345-style names are not easy to remember. – Szabolcs Mar 22 '14 at 16:57
How do I do that? – user13136 Mar 23 '14 at 5:28
  1. Go to Format -> Edit Stylesheet

  2. Under "Choose a style" choose "Output"

  3. Select the cell bracket of the new cell that appears

  4. Press Ctrl+Shift+E (Command+Shift+E on a Mac) to show the cell expression

  5. Change Cell[StyleData["Output"]] to Cell[StyleData["Output"], ShowCellLabel -> False]

  6. Press Ctrl+Shift+E again

  7. Close the stylesheet window
