Re: SCS data conversion?? -- LINUX5250

Thank you for the links! They have already been informative.

Hi,

If you want to do this from an RPG program, I wonder if you could just
use the Host Print Transform API?  (QwpzHostPrintTransform)  you can
find more information about that, here:

http://publib.boulder.ibm.com/pubs/html/as400/v4r5/ic2924/info/apis/QWPZHPTR.htm

I've already used this API to read an SCS stream file and convert it to
plain text, so I know it can be done.

When I did it, I used the "manufacturer type & model" of *WSCST and set
the WSCST library/name to *LIBL/QWPDEFAULT.


Otherwise, you'll probably need to write your own "scs2ascii" program
in RPG.  You could do so by copying the way our scs2ascii.c works, or
if you want to understand it better, there's info about the SCS data
stream on the internet.

The best source i've found for the format of the SCS data stream is
the "IPDS and SCS Technical Reference" from IBM.  You can find it
here:
http://publib.boulder.ibm.com/prsys/pdfs/54453124.pdf

The chapter titled "AS/400 Non-IPDS" is the SCS codes.

Here's another source, which is easier to read, but less complete:

Good Luck!

I'm looking forward to reading the posts since I have been a Linux

You guys seem to be the only ones that have figured out the same problem
we are having. Our solution can not have a Linux or Windows solution,
but rather we need either a Java or RPG solution. So I just hope you
guys can get me started.

Two of us have been working on an archive retrieval solution, and we
have managed to retrieve Raw SCS data from an archive (amoung other
formats).  The data is read to a buffer in an RPG program.  Typically,
this data is written to a file on the IFS, and a Java program is then
reading it and streaming it to a browser for viewing.  This works great
for AFP, Spooled Files, etc..., but the SCS data just gives us garbage.

I've noticed that the tn5250 has something called scs2ascii, scs2pdf,
etc.  So someone has figured out how to translate raw SCS data into
other formats.  How could we get started doing this?  IBM support has
not been helpful at all. In Java, I've tried reading it in and then
writing it to an OUTQ using the SpooledFileOutputStream class, but all I
get is garbage. My buddy has tried several API's via RPG with no success.

Is there a Java or RPG port of scs2*?  If not, how would someone get
started writing this conversion from scratch in Java or RPG?  How big of
a project would this be?  Is there a better way to do this?

Thanks for any help!
