Without "to" clause, current-row will print out the current row number. First row is numbered 1. With "to" clause, the row number is stored into variable <current row>. current-row must be within a <a href='https://golf-lang.com/run-query.html'>run-query</a> loop, and it always refers to the most inner one.<br/>
