RE: ASCII to EBCDIC

[Nathan Andelin <nandelin@xxxxxxxxxxxxxxx>]

It would kind of surprise me if there wasn't something built into the socket
APIs to handle the conversion.  Although I've not done socket programming in
RPG, IBM usually supports conversion at the communication level.  The Client
Access APIs are a good example.  If not, then you might try the QDXLATE API.
Its documented in the System API Reference.

how can i translate data from ASCII to EBCDIC.  I am doing some socket
programing usin RPG/ILE.  The only problem I am having is that PC is sending
me ASCII data on my port.  I can read it but its not in EBCDIC.

Please help
Thanks

Here is a little more information on why at least one person thinks that
this is
a good thing (a feature, not a bug).

I am not sure what you are getting at in your reply, Gary.  I gather that
there
is a persistent connection, and the problem (if it is a problem) is in
closing
the connection without closing the statements.

I am curious how other implementations handle this.  Are the connection and
the
statement synchronized?  And what about Netscape's Suitespot server?

Yes! releaseIBMConnection() just puts the connection back in the pool-- the
connection is not necessarily closed at this point. It is very reasonable to
assume that some applicatoins might create a connection pool where
statements within the connections within the pool could be used more than
once. I am not sure how it would be implemented-- e.g., how would the second
user of a connection know that the statements have already been allocated?
One way might be to subclass the Connection and add some functionality for
application-specific statement management to the subclass, and let the pool
be instances of the subclass.. depending on the application at hand, this
could be a real performance booster.

Regarding the original problem of closing statements that will no longer be
used, be sure to do something like this:

// [statement opened]
try {
  // [use statement]
} finally {
  stmt.close();
}

to ensure that it will ALWAYS be closed no matter what might go wrong in
between..
