主题：请教DEBUGFILE和DEBUGFILE2

//代码如下：

INPUT: lots(1,1,10,1);

VARIABLE: signal := 0;
ss := signal;

h_1 := ref(h,1);
l_1 := ref(l,1);

zjj := (h_1 + l_1) / 2,NODRAW;

if ss = 0 and h >= (h_1 + l_1) / 2 then BEGIN
   DEBUGFILE('C:\TEST1.TXT','ss=%.0f',ss);
   DEBUGFILE('C:\TEST1.TXT','h=%.0f',h);
   DEBUGFILE('C:\TEST1.TXT','zjj=%.0f',zjj);
   signal := 1;
   myprice := (h_1 + l_1) / 2;
end;

if ss > 0 and l <= l_1 then BEGIN
   DEBUGFILE('C:\TEST1.TXT','ss=%.0f',ss);
   DEBUGFILE('C:\TEST1.TXT','l=%.0f',l);
   DEBUGFILE('C:\TEST1.TXT','l_1=%.0f',l_1);
   signal := 0;
   myprice := min(l_1,o);
end;

//后台部分
if ss < 0 and signal >= 0 then begin
 tsellshort(workmode = 1, -ss * lots, MKT);
 sellshort(workmode = 0, -ss * lots, LIMITR, myprice);
 ss := 0;
end;
if ss > 0 and signal <= 0 then begin
 tsell(workmode = 1, ss * lots, MKT);
 sell(workmode = 0, ss * lots, LIMITR, myprice);
 ss := 0;
end;

tbuy(workmode = 1 and ss < signal, (signal - ss) * lots, MKT);
buy(workmode = 0 and ss < signal, (signal - ss) * lots, LIMITR, myprice);
tbuyshort(workmode = 1 and ss > signal, (ss - signal) * lots, MKT);
buyshort(workmode = 0 and ss > signal, (ss - signal) * lots, LIMITR, myprice);
