A character string containing the constant value desired, note that this string can be a numeric value (e.g., "25"), a fully defined expression (e.g., "p5=25"), an existing expression name (e.g., "p5"), or an expression string (i.e.,"p5+p7"). If the fully defined expression exists then the expression will be edited. If the expression name does not exist then an error occurs. Otherwise an expression is created.
