Re: Base64 decode

@Greg
I usually can see the content of all variables during debug, no matter the
ccsid they are defined with; you shouldn't have any problems with it.

As per sending the same variable content directly to the Zebra printer I'd
rather save all data into a table (just in case) with no utf-8 fields and
then write to the printer from this table.

When you move one variable into another, if they are defined with different
ccsid the system itself takes care of the conversion, so my whole process
uses utf-8 variables just when needed.

Hop it helps again.

Maria,

Thank you!

So changing my DECODED variable to CCSID(*UTF8) allowed me to write the
data to an IFS file and see that it was correct. But I couldn't "see" data
in the variable DECODED while in debug?

Ultimately, I need to send this directly to a Zebra Label printer (decoded
data is ZPL II). So I'm not sure if I want to write it to the IFS then
send it to the printer, or just send it directly to the printer. It might
be useful to have a copy of the data (for a period of time) in case
printing the label fails for some reason.

Subject: Re: Base64 decode

Hi all,
I had the same need, so at first, I tried SQL native function. For some
reason that I couldn't explain, when I had to end the job (a batch job) it
took ages (literally, more than 10 minutes) to end. Then I tried SK
routines.
That's how I am successfully using it:

dcl-s b64EncodedVar char(64);
dcl-s b64DecodedVarUtf8 char(64) ccsid(1208); // utf-8
dcl-s b64DecodedVarLen uns(10);
dcl-s userName char(20);

docNode = YAJL_string_load_tree(requestData.data: errMsg);
if errMsg = '';
node = YAJL_object_find(docNode : 'username');
b64EncodedVar = YAJL_get_string(node);
b64DecodedVarLen = base64_decode(
%addr(b64EncodedVar)
: %len(%trim(b64EncodedVar))
: %addr(b64DecodedVarUtf8)
: %size(b64DecodedVarUtf8)
);
username = %subst(b64DecodedVarUtf8: 1: b64DecodedVarLen);
endif;

Hope it helps.

Do I define them with specific CCSIDs?

You can use SQL

Do I need to do something with the data before decoding?
