Page orientation when combining multiple postscript files to a pdf file

Question

Hi
I'm having problems with the orientation of my pages when I generate pdf's from multiple postscript files.
I have 3 postscript files that need to be merged into 1 pdf, and they contain a mixture of portrait and landscape pages.
To create the pdf, I use the following code (because i have lots and lots of pdf files to produce)...
/prun { /mysave save def
     dup = flush
     RunFile
     clear cleardictstack
     mysave restore
} def
(D:/example/fileA.ps) prun
(D:/example/fileB.ps) prun
(D:/example/fileC.ps) prun
... however, when I run the above code (by saving the text file into the /in directory of a watched folder), whilst I get a pdf, the page orientation isn't right.  For some reason, the first few pages are oriented correctly, then after about page 7 everything is portrait no matter what.
The funny thing is, when I simply double-click on one of the postscript files (eg. fileA.ps), distiller changes it to pdf and the orientation is perfect for each file separately (fileA, fileB, fileC).  Even when I run the above code for just one ps file it works.  But as soon as I put all 3 sub-files together it doesn't orient properly.
I've tried activating and de-activating auto-rotate in the PDF settings, as well as the DSC options in the Advanced tab, and whilst these changes do affect the pdf I get when I simply double-click a certain postscript file, it seems to have no effect when I try to combine the 3 files with the code above.  I still end up with the first few pages oriented correctly, then after about page 7 everything is portrait.
Hope someone can help.

Ok i successfully generated my PDF files.
Now I'm having difficulties merging them. I use a DDX file named LiveCycleInput.ddx
What I do (everything in LiveCycle Workbench):
1) FileReader to open the .ddx file as a document (successfully)
2) Store the read document in a process variable (successfully)
3) Assembler.invokeDDX with following arguments:
Document DDX = process variable (read in 2)
OutputResult = "AssemblerResult" processVariable which has type AssemblerResult as specified by the documentation
Errorlog
Everytime I run the process I get the following stacktrace in my server's logfile:
... 119 more
Caused by: com.adobe.internal.pdfm.CollateralNotFoundException: DDXM_S14017: A <PDF> source document is required, but no documents were found for {PDF source="testFileDoc.doc.pdf" baseDocument="true"}.
at com.adobe.internal.ddxm.ddx.pdf.PDFSource.getOrderedInputDocs(PDFSource.java:595)
at com.adobe.internal.ddxm.blueprint.pdf.SourceSegment.addDocumentsForAssembly(SourceSegment .java:91)
... 125 more
The .ddx file is stored in the same path as my generated .pdf files are stored.
Content of my DDX file (full copy paste)
<DDX xmlns="http://ns.adobe.com/DDX/1.0/">
<PDF result="testFileMerged.pdf">
  <PDF source="testFileDoc.doc.pdf"/>
  <PDF source="testFileJpg.jpg.pdf"/>
  <PDF source="testFileOdt.odt.pdf"/>
</PDF>
</DDX>
Note that the DDX file is read from a network drive(!!) the source PDF files are in the same folder as the ddx file (hence no further path-links).
Adding network paths to the source & result pdfs does not change a thing.
All PDF Files apart from the result pdf fiile are present in that same folder
I consulted the DDX reference multiple times and this is the simplest ddx that should work ... but it doesnt.
Can anyone help me?
