Text: PrintTokenAndColon

[NES version, Bank 0]

       Name: PrintTokenAndColon                                      [Show more]
       Type: Subroutine
   Category: Text
    Summary: Print a character followed by a colon, ensuring that the colon is
             always drawn in colour 3 on a black background

    Context: See this subroutine in context in the source code
 References: This subroutine is called as follows:
             * fwl calls PrintTokenAndColon
             * TT25 calls PrintTokenAndColon




 The colon is printed using font style 3. This draws the colon in colour 3 on
 background colour 0 (i.e. green on black), but without using the normal font.

 This ensures that the colon will be drawn in green when the colon's tile falls
 within a 2x2 attribute block that's set to draw white text (i.e. where colour
 1 is white). This happens in the Status Mode screen in French, and in the Data
 on System screen in all three languages.



 Arguments:

   A                    The character to be printed
