We are using PCML in order to invoke a AS/400 COBOL program and return data
back. Can any one tell, how to pass " record " (AS/400 Physical file record)
as linkage variable using PCML.
I knew that program call will allow a record to be passed as an argument (
if record is converted as byte array and we set the byte array as program
parameter),
How to pass same argument using PCML, how should I code a record argument in
<struct> tag.
My Cobol program can take record as linkage section ( 01 record-area)
Any suggestions ?

Note IFSFileInputStream and IFSFileOutputStream extend their
java.io
counterparts. This makes it possible to use java.io buffers
and readers
with Toolbox classes. For example,
AS400 system = new AS400();
IFSFileOutputStream outputStream = new
IFSFileOutputStream(system,
"/daw.temp");
PrintWriter writer = new PrintWriter(outputStream);
for (int i=0; i<10; i++)
{
writer.println("Hello Java");
}
writer.flush();
IFSFileInputStream inputStream = new
IFSFileInputStream(system,
"/daw.temp");
InputStreamReader inReader = new
InputStreamReader(inputStream);
BufferedReader reader = new
BufferedReader(inReader);
String text = reader.readLine();
while (text != null)
{
System.out.println(text);
text = reader.readLine();
}
But, there is one hole in our support that we have on our
todo list to fix.
We have InputStream and OutputStream objects that convert
text between the
ccsid of data stored in the file and Unicode. For example,
if the file
contains ebcdic data you can use IFSTextFileInputStream to
read that file.
The class will automatically convert data from ebcdic to
unicode and stuff
the data in a String object. Don't see an obvious way to
hook up an
IFSTextFileOutputStream with a buffered reader. It will
compile but I
think the reader will call the method that gets bytes, not
Strings.
Getting bytes will get the raw ebcdic data, not the
converted unicode
strings. Maybe your text is not in ebcdic so you don't care
but I wanted
to point this out just in case. A way around this problem
(if the file is
small) is to read the entire file into a single String
object, then create
a StringReader over the String. Hope this helps,

It is a text file on IFS. I tried to use
IFSFile,IFSFileInputStream,
IFSFileOutputStream, etc. but there isn't a readLine()
method in these
classes. I want to be able to read one line at a time.
With IFS file
access classes above, you can only read for a specific
amount of byte at a
time not per line basis.

What type of file are you reading from?
(1) If from a stream file in the integrated file system and
on the AS/400
use java.io.*. If on a client try the Toolbox IFS classes
(IFSFile,
IFSFileInputStream, IFSFileOutputStream, etc.). They work
just like the
java.io classes.
(2) If reading from a database file use JDBC or Toolbox
record-level
database access.

What is the equivalent technique to read a record in AS400
Toolbox like the
java.io. readLine() method?
