Need username printed at top of page

[Patrick Young]

Things are going well. Thank you, Helge! Now I just have a couple PostScript questions. I added (Username: ) show before _WM_str show and (, Job ID: ) show after it. It prints Username: somename, Job ID: so I haven't blown things up yet. I tried making a call to the job-id variable but couldn't get it to work. How do I do that. Also, now the text begins in the center but moves towards the right side of page. How can it be truly centered again after I added those extra lines?

Thank you!
