Rename column in a for loop

Zihao

Hi 

I am trying to rename Column(3) as  "Step i" for( i = 1, i<=3, i++), and I was using the script like below. 

files={"path1", "path2", "path3"}
for (i =1, i<=3,i++,
dt = open(files[i]);
newname = "step"||i;
Column(3) << setname(newname)
);

 However, it doesn't work. It seems that the "newname" is not defined properly (I tried to show(newname) and nothing happened). 

 

Can someone help me with the correct definition of the new name with "i" in it?

 

Thanks!

The variable "i" is numeric and in order to be used in a concatenation, it needs to be a character variable.  See below

files = {"path1", "path2", "path3"};
For( i = 1, i <= 3, i++,
	dt = Open( files[i] );
	newname = "step" || Char( i );
	Column( 3 ) << setname( newname );
);
