BUG report: Distiller v.8.1.0 erroneously execute i/o-operations in PostScript programms

Question

Distiller v.8.1.0 erroneously execute i/o-operations in PostScript programms (WinXP SP3 & Win2K3 RC1 SP2 platform).
Execution of the PS-code, contained file i/o operaions (see
i PLRM 3rd edition
, pp.73-87)
c %*************************** PS-File *********************************
c (c:\\temp\\File1.txt) (w) file closefile % Open file for write and close it
c %*********************************************************************
(or others file write ops.) produce invalidfileaccess error:
b =============== Distiller LOG =====================

Execution of the file read operations (file exist!)
c %*************************** PS-File *********************************

or
c %*************************** PS-File *********************************

It doesn't matter, in what folder operation is carried out system %TEMP% or User %TEMP% (not in %HOMEPATCH%!) file i/o
b don't work.
With mentioned [in KB http://www.adobe.com/devnet/acrobat/downloads/Acrobat_SDK_readme.html ] command line switch «-F» all works correctly.
This "feature" of the Acro8 (and Acro9? see http://www.adobeforums.com/webx/.59b69fa1 ) does impossible execution of the PostScript programs of variable data print.
What to do that Distiller the beginnings it is correct to work (file i/o into %TEMP%-folders) without «F»-switch?

Answer 1

I don't use Acrobat SDK, i make PostScript-programs for the var.data print, f.e. labels with wire name, numbers, barcode etc.; Distiller plays role RIP, carrying out the program.
As a data source at execution of these programs files of various formats can be used: ANSI/UNICODE text, binary (f.e. PhotoShop-RAW data), PostScript (f.e. «print-in-file» from Illustrator) file and others. The same programs can write what or given on a disk (tmp-files), for example the pointer to the data in a source file or the debug information.
For me has surprised that in 8 Acrobat'е all it has suddenly ceased to work, though in early versions and ghostScript all is fulfilled correctly. I have assumed that obviously developers had been limited possibility of data write/reading a disk and, most likely by a TEMP-folder. However even in the TEMP-folders setted by means of a variable %TEMP% of write operation at execute of PostScript-program by Distiller it was not possible to make. Also attempt to read/execute a file which is in a TEMP-folder was unsuccessfully completed also.
During search in the Internet I have found article specified above ( http://www.adobe.com/devnet/acrobat/downloads/Acrobat_SDK_readme.html ) in which it is underlined possibility by default operations of file I/O in a TEMP-folder, however impossibility it to make contrary specified in this article, have forced me to write to this forum so it is read by Acrobat developers.
