執行區看不到print指令結果

在警示腳本中要如何將print顯示至訊息區? 下面的腳本第一個print可以成功寫入檔案，可是第二個就沒看到顯示。是什麼地方需要設定嗎?謝謝

input: Length(9,"天數"), RSVt(3,"RSVt權收"), Kt(3,"Kt權數");
variable: rsv(0), k(0), _d(0), days(0), j(0);

stochastic(Length, RSvT, Kt, rsv, k, _d);
j=3*_d-2*k;
//成功
print(file("c:\temp\2.txt"), currentDate , currentTime, symbolName, close, closeD(0), j);
//不顯示
print(currentDate , currentTime, symbolName, "close=",close, "closeD(0)=",closeD(0),"k=",k,"_d=",_d, "j=",j);
