Splitting a text string into multiple display line in an inputbox in a Google Macro

Question

Please excuse any stackoverflow mistakes as I am not a developer. I currently have a Browser.inputBox statement in a Google Macro that I would like to break-up the text into multiple display lines using a linefeed or some special characters within the text string (i.e.; concatenate a function within a text string). The macro language does not recognize the CHAR function [CHAR(10)].

Example:

var rangename = Browser.inputBox("Enter Range Name to Copy: (e.g.; A1, G45:G46, G45:H45, G45:Z203)");

I would like the question on the googles screen to look as follows:

    Enter Range Name to Copy:

    (e.g.; A1, G45:G46, G45:H45, G45:Z203)

Any suggestions appreciated. Thanks
