You can stick any data you like in a stream file, in any CCSID, and
even include data from multiple CCSIDs in the same stream file. It's
all under your programmatic control so you can do anything.
Where you'll encounter a problem is with tools that expect a stream
file to contain data in only one CCSID. That CCSID is an attribute of
the stream file object (at least on properly designed systems that
allow for multiple CCSIDs--on others it's either a guess based on the
first N bytes of data or an assumption about the content).
PDF is an ASCII text format but because the real content (as opposed
to the file structure) can be in one or more code pages it really
should be considered a binary format. I'd tag them with 65535 to make
it obvious but I expect you'll find 819 to be more transparent given
that you'll likely be sending the file to an ASCII system or viewing
it on one.
One quick question.
You are correct I was using CPYTOSTMF to get the file to the IFS (or
file
server)
Would CPYTOSTMF work if I converted to ASCII using both code pages
Then using the CPYTOSTMF specify CVTDTA(*NONE)
Because no conversion is required if I already converted everything to
ASCCII when the file was created in the program
Probably, but if you're going to the effort of correctly converting to
the appropriate ASCII CCSIDs then just write out directly to the
stream file. Avoid the clumsiness of building an intermediary database
file and using CPYTOSTMF. It will be faster to write directly (as long
as you write reasonable chunks of data) and it will likely be clearer
as well (due to less steps involved) and good practice for stream I/O.
