Ｃからの利用
 int	PiLoad(char *name,int buff,int Size,int X,int Y,int tone,int option)

PASCALからの利用
 functuon PiLoad( name:string; buff,Size,X,Y,tone,option:integer):integer;

Assemblerからの利用
 piload0 proc near
	es:dx	= name(asciz)
	ds:0	= buff
	si	= size
	bx	= x
	cx	= y
	al	= tone
	ah	= option

 引数
	name	ファイル名
	buff	バッファのセグメント
	Size	バッファのサイズ
	X	表示アドレスのＸ座標
	Y	表示アドレスのＹ座標
	tone	トーン（１～１００％）
	option	オプション（下記のビットで指定）通常は15(01111b)
	   (lsb)0 .. パレット設定	する／しない = 1/0
	   	1 .. 常駐パレット設定	する／しない = 1/0
		2 .. コメント表示	する／しない = 1/0
		3 .. 画面設定		する／しない = 1/0
