Renaming Columns

Community Support

I’m looking for a way to rename many columns all at once. For example:

 

t:(a:til 5;b:0;c:3)

Let’s say I want to add “US” to all coumns, I know I can use xcol

 

t:USaUSb`USc xcol t

 

But what if I have dozens of columns?

 

Is there a way to simply say, "Add “US” to the front of all column names?

 

Thanks

Hey Jake,

How about this.

t:(`$(“US”),/:string cols t) xcol t

Perfect.
