 Usage 

 DRAWBOX is useful for creating attractive screen displays in batch files. 
 

 For example, to draw a box around the edge of an 80x25 screen with bright 
 white lines on a blue background: 

 
         drawbox 0 0 24 79 1 bri whi on blu fill blu
 

 See Colors and Color Names for details about colors and notes on the use 
 of bright background colors. 

 If you use ZOOM, the box appears to grow in steps to its final size.  The 
 speed of the zoom operation depends on the speed of your computer and 
 video system. 

 If you use SHADOW, a drop shadow is created by changing the characters in 
 the row under the box and the 2 columns to the right of the box to normal 
 intensity text with a black background (this will make characters 
 displayed in black disappear entirely). 

 The row and column values are zero-based, so on a standard 25 line by 80 
 column display, valid rows are 0 - 24 and valid columns are 0 - 79. 

 DRAWBOX checks for valid row and column values, and displays a "Usage" 
 error message if any values are out of range. 

 Unlike DRAWHLINE and DRAWVLINE, DRAWBOX does not automatically connect 
 boxes to existing lines on the screen with the proper connector 
 characters.  If you want to draw lines inside a box and have the proper 
 connectors drawn automatically, draw the box first, then use DRAWHLINE 
 and DRAWVLINE to draw the lines. 

 DRAWBOX uses the standard line and box drawing characters in the U.S. 
 English extended ASCII character set.  If your system is configured for a 
 different country or language, or a font which does not include these 
 characters, the box may not appear on your screen as you expect.
