Hi...i here again! :p
I try to do a routine what all columns in a worksheet are subtracted for another worksheet.This another worksheet have only 2 points, taked by the GetPts comand.So, i have to do subtration with interpolation (--O).A piece of my code is below:
"Copia" is the main worksheet and "line_b" is the "another worksheet" .
 
create line_B -d 2;
GetPts -n line_b 2;

for (jj=2;jj<=%W!wks.ncols;jj++){
	
 	
	%(copia,jj) --O line_b;	   
	
	   
	}


Does work without "for" too....
please help me!

The for-loop executes before points are selected and all Y columns in Copia probably end up with missing values "--". (See the Notes in the programming guide's description of the GetPts command.) Use the EndToolbox macro to delay subtraction until two points are selected...

def EndToolbox
{
%W=Copia;
for (jj=2;jj<=%W!wks.ncols;jj++)
{
%(%W,2) --O line_B;
};
layer -a; // rescale graph layer
};
create line_B -d 2;
GetPts -n line_B 2;
