Mnemonics "W"

== (Wallpaper Bitmap) ==
<pre> 
Mnemonic:  (WallpaperBitmap = FileName)  
Discussion:  Creates a wallpaper (background) bitmap by tiling the specified bitmap file to fit the currently active Comet window.  
</pre>

== (Wallpaper Clear) ==
<pre> 
Mnemonic:  (WallpaperClear)  
Discussion:  Clears the wallpaper bitmap in the currently active Comet window to its original state. That is, it will be re-tiled to eliminate any drawing that had been previously done.  
</pre> 

== (Wallpaper Color) ==
<pre> 
Mnemonic:  (WallpaperColor = Red,Green,Blue)  
Discussion:  Creates a wallpaper (background) bitmap using the specified RGB colors to fit the currently active Comet window. 
Colors are represented by 3 (Red, Green, Blue) color intensity values, each ranging in value from 0 (no color - black) to 255 (max color - white). 

Red     ! Specifies the amount of RED
Green   ! Specifies the amount of GREEN
Blue    ! Specifies the amount of BLUE
</pre>

== (Wallpaper Remove) ==
<pre> 
Mnemonic:  (WallpaperRemove)  
Discussion:  Removes the wallpaper bitmap in the currently active Comet window, restoring the window to its normal QCRT operation.  
</pre>

== (WC) ==
<pre> 
Mnemonic:   (WC)  
Hex equivalent:  "@0E07@"  
Discussion:  The (WC) control code writes to the control line (a.k.a. "message line") of the controlling terminal. Subsequent data on the current write is displayed on the control line at the bottom of the screen display. 
Typically, the control line is used to display special messages and/or warnings. 

Note: The (WC) control code sends messages to the controlling device only, not to other terminals or devices. To send a message to another terminal, you must use the DOSRW function, explained in the DOS Function Calls section. 
 
Example:  a. 100 FORMAT (WC);"This is a message."
   .
   PRINT (0,100)

b. PRINT (0) (WC);"This is a message."
</pre>

== (Who Has File) ==
<pre> 
Mnemonic:   (Who Has File=server-number, filename, directory)  
Discussion:   
Example:  
</pre>

== (Window Title Background) ==
<pre> 
Mnemonic:   (Window Title Background=ARG1$,ARG2)  
Hex equivalent:  --  
Discussion:  This control code displays text on the top border line of the current Comet window. 
ARG1$ is string (constant or variable) containing the text to be displayed in background characters on the top border line of the current Comet window. 

ARG2 is a number (constant or variable) containing the horizontal starting position where the title text will be displayed (position 0 is the left-hand column). 

Also see (Window Title Foreground). 
 
Example:  a. 100 FORMAT (Window Title Background="Title line",5)
   .
   PRINT (0,100)

b. PRINT (0) (Window Title Background="Title line",5)

</pre>

== (Window Title Foreground) ==
<pre> 
Mnemonic:   (Window Title Foreground=ARG1$,ARG2)  
Hex equivalent:  --  
Discussion:  This control code displays text on the top border line of the current Comet window. 
ARG1$ is string (constant or variable) containing the text to be displayed in foreground characters on the top border line of the current Comet window. 

ARG2 is a number (constant or variable) containing the horizontal starting position where the title text will be displayed (position 0 is the left-hand column). 

Also see (Window Title Background). 
 
Example:  a. 100 FORMAT (Window Title Foreground="Title line",5)
   .
   PRINT (0,100)

b. PRINT (0) (Window Title Foreground="Title line",5)
