Actually using .\NUL as source is a Bad Idea - it will deliver an infinite amount of empty lines. This is a useful technique in scripting, but outside the current discussion. You can use a Transformer stage with a stage variable and a constraint of @INROWNUM = 1 to generate a single row. The Transformer stage needs no input link in a server job, provided it has something to do, such as evaluate a stage variable. Naturally, the value generated must be put onto a column on the output link.
