void test()
{
string str,str1;
str1="data1";
//LT_execute("win -a data1");
Worksheet wks(str1);
Dataset tempcol(wks,0);
tempcol.GetName(str);
LT_execute("stat.ds.data$=str");//LT_execute("stat.ds.data$=tempcol");
LT_execute("stat.ds()");
double dbl1,dbl2;
dbl1=LabTalk.stat.ds.quartl25;
dbl2=LabTalk.stat.ds.quartl75;
int num=LabTalk.stat.ds.size;
}


why is it right sometimes,but is worong sometimes?

How to use stat.ds?
why is it both zero about dbl1 and dbl2?

HI,
I cannot reproduce this problem. The following are my testing codes, could you try again? 

void test()
{
	Worksheet wks("Data1");
	Column tempcol = wks.Columns(0);	
	string str, strPage;
	wks.GetPage().GetName(strPage);
	tempcol.GetName(str);
	
	str = strPage + "_" + str;	
	str.Format("stat.ds.data$=%s",str);
	LT_execute(str);
	out_str(str);//Now, str is "stat.ds.data$=DATA1_A"
}

This is a bug maybe !
When I debug the codes and the breakpoint is at the line:
LT_execute("stat.ds.data$=str");//LT_execute("stat.ds.data$=tempcol");

I find the value of thevariable "str" is "Data1_A",but the value of dbl1 and dbl2 are both zero.
When I modify my codes as cpyang said:
tempcol.GetName(str);
str.Format("stat.ds.data$=%s",str);

then,the value of "str" is yet "Data1_A", but the result are right.

Maybe you should use pure C code.

To use LabTalk in OC code, you need to know LabTalk well.
your line

LT_execute("stat.ds.data$=str");

tells LabTalk that you are doing work with a Dataset called "Str", and I suppose there is no such dataset in your Origin session. More likely, you need to write code like

string strDataset;
strDataset = str1 + "_" + str; // assume that str = Col name

string strLT = "stat.ds.data$=" + strDataset;

LT_execute(strLT);


It looks like you need to do percentile calculation, maybe you can try the Data_percentiles function, which you can find by looking up OC Language Reference and Global Functions inside statistics.
