RE: IFS STMF file read - Codepage problem?

Cool. That's why you need to post the complete code in the list. :)
Hey, do you have a PGP decryption routine on the 400 or will you just use a
PC-based tool?

Subject: RE: IFS STMF file read - Codepage problem? - resolved

Bob/Scott - Thanks!

After I got ErrNo working - it was 3021 - wrong number , so I looked 
closer at the code and I was opening the file using...

        fd = open('/testfile.asc':
                   O_TEXTDATA);

but should have been opening it using...

        fd = open('/testfile.asc':
                   O_RDONLY + O_TEXTDATA);

When I opened it that way - then it opened just fine, and I was able to 
read the first few bytes.


Bob,

The PGP encrypted files that we work with are plain ascii.  The first line 
of each file is...
'-----BEGIN PGP MESSAGE-----                       '

then the encryption version number, then encrypted data.  I'm processing a 
folder that has both plain text reports and encrypted PGP files.  So I was 
reading the folder and then the first few bytes of each file to decide if 
the file needed to decrypted.


Thanks for your help guys.

How are you testing the first few bytes to see if it is encrypted?
Why not just open the file as binary (like you already are) then convert 
the
data to your job's CCSID then "test the first few bytes"?

O_TEXTDATA automatically converts the IFS file's codepage to the job's
codepage, but it can only do that effectively with plain ASCII text. It 
also
adds linefeed characters to the data, so the data will not be the same as 
it
is on the IFS when read by O_TEXTDATA. I use O_TEXTDATA only for text 
files.
Perhaps O_TEXTDATA is detecting something in the file that prohibits it 
from
being able to read the file as plain ascii text and is giving you an error
on the open or read.

But I'm not sure that it needs to be decrypted at the point that I'm 
reading the file.  I'm reading the first few bytes to find out if the file 

is encrypted or not.

(still working on the error number - should have it soon)...

Thanks!

You can open non-"plain" ASCII with O_TEXTDATA? Hmmm?
I don't think he should be reading the file as O_TEXTDATA, but rather, 
read
it as binary, decrypt it, then convert the decrypted text which should at
that point be in ASCII or CCSID 437 (8-bit ASCII US PC) to EBCDIC.

Yep, that looks like valid ASCII. You need to get O_TEXTDATA working, 
somehow. Please let us know what the value of "errno" is when you find 
out.
