;   Font is saved in the file named DEMO.ASM.  To use the font, you must call
;   interrupt 10h, function 11h, sub-function 10h to load up the font.
;   
;   The following are the parameters needed to call the function:
;  
;                 AX  =  1110H      (ah = 11H, al = 10H)
;		  BH  =  bytes per character 
;		  BL  =  block to load to.  (use 0)
;		  CX  =  number of character defined by table
;		  DX  =  starting character value
;		  ES  =  segment of the table (use Seg())
;		  BP  =  offset of the table (use Ofs())
;
;   Notice: The character should always be loaded immediately after setting
;           the Video mode.  If it is not called immediately after the video 
;           mode is set, some side effects may occur.  We have experienced 
;           some palette errors when this function is called without setting
;	    the video mode.  The appearance of this effect is intermittent and
;           unpredictable, but it may be avoided by following the recommend-
;	    ation in this paragraph.
;   
;   FONT MANIA will supply you with the height of the font.  It is defined
;   by your label name with "_POINTS" added at the end of the string.  For
;   example, if your label reference is called DEMO, then DEMO_POINTS will 
;   represent the bytes-per-character of the font (the height of the font).
;   
;   Set the CX to 256 if you want to load the whole font. If you want to 
;   load only part of font,  Set CX to the number of the character you want
;   to load, and set DX to the first character you want to load.
;   
;   For example, suppose you want to load characters 65 to 88 (A to Z) and
;   the label reference is DEMO.  Here are the parameters needed:
;   
;		 AX  =  1110h
;		 BH  =  DEMO_POINTS
;		 BL  =  0
;		 CX  =  24               ( 24 characters to load )
;		 DX  =  65               ( first character to load )
;		 ES  =  SEGMENT DEMO
;		 BP  =  OFFSET DEMO
;		 
;   See below for examples of how to set the registers.
