\ - Extends a single Matrix command over a number of lines.

\ - When working within a Command Prompt Window it is sometimes convenient to write a command over one or two lines. If a backslash ("\") is placed at the end of a line and the return key pressed this will allow further input to be entered. Characters entered after the \ are ignored. If the backslash character is contained within a quoted string it has no special effect.
