Here are a few session snippets that show how Java and the iText Open Source
package from Bruno Lowagie can be used on MPE/iX to convert flat files or
spoolfiles (without the CCTL info) to PDF with a fairly simple little program.

Have fun, Lars Appel, May 2002

:# The easiest way to view the .txt and .pdf files is from a PC via Samba/iX


:# Note that by reading the spoolfile with a Posix based tool like /bin/tr,
:# the CCTL information will already be stripped out fairly early during the
:# process, so the resulting PDF file will not show it in the first column.

:# If you prefer to have the CCTL info visible in the PDF file, you can try
:# a slightly modified approach that combines /bin/tobyte and /bin/tr to get
:# the input file for the PDF conversion step. The benefit of /bin/tobyte is
:# that the CCTL bytes will be visible in the first column of each line, but
:# you should make sure to get rid of the ASCII NUL chars by using /bin/tr
:# to replace them with blanks (happens to match CCTL %040 by the way ;-)
