BOLD, BLINK, REVERSE, UNDER, ALLOFF

The following format subcommands assign attributes to characters being printed in order to highlight text and diagrams:

 BOLD       Brightens printed characters
 BLINK      Causes printed characters to blink on and off
 REVERSE    Creates characters on a reverse background 
 UNDER      Underlines characters 
 ALLOFF     Switches off all active attributes

Any combination of attributes can be used.

Example:

  PRINT @(REVERSE),"THIS WILL BE HIGHLIGHTED",@(ALLOFF)

Note: Not all attributes are supported on all terminals. Previously selected terminal options (e.g., cursor type) may affect the attributes. If an attribute is not supported on the selected terminal, it will have no effect.
