Hi, there!

[ I posted this article some time ago without any reaction.
  So I try it again - I think, it has not been posted :-) ]


I am developing an applications for generating tabulars. The output
contains several pages in one file.

As I know, the structure of the code matches the rules in 'Document
Structuring Conventions' in the Postscript Reference Manual.

So far, everything is o.k. Our Laserjet prints all pages, the linotype
attached to a mac, too.

If I do a preview on screen using the NeXT Previewer or Ghostview/
Ghostscript, I can see all pages. I can zoom them, too.

Now the error: If I am previewing the last page in my file, I can not
get back to other pages or zoom it. A postscript error occurs.

I know, that both previewers can do this, because I have got many
postscript documents containing several pages. All document exept my
own are handled correctly :-(

I looked at the structure of the working documents, but I can not see
any difference that could be the reason for this behavior.

My suggestion is, that I have to do something in the pager trailer (so
far, I do not use one).

Please: If you have got an idea, what I am doing wrong, mail me. 

I will summarise you answers, If you want.

This is an example of my postscript files. I deleted uninteresing
code. If you need to see the whole file, please let me know.
