Extending your RPG application set
In areas where RPG native support is weak or non-existent
• e.g. XML, E-mail, Sockets, CGI
- All of these can be done via native support (XML)
- Or open source or third-party tool kits
- But can be complex to use
¨ And for some people the lack of formal support is an inhibitor
By providing new interfaces to native functions
• I5 Toolkit and DB2 support provide comprehensive access
• Integrate system functionality into:
- Web services
- New browser applications

Comparing XML Processing in RPG and PHP
At first glance both programs look very similar
• But all is not quite as it seems

/Free
/Free
XML-INTO company %XML( XML_Input1: 'doc=file case=any' );
XML-INTO company %XML( XML_Input1: 'doc=file case=any' );
for i = 1 to xmlElements;
for i = 1 to xmlElements;
dsply company(i);
dsply company(i);
endfor;
endfor;

<?php
<?php
$Customers = simplexml_load_file(quot;Partner400Customers.xmlquot;);
$Customers = simplexml_load_file(quot;Partner400Customers.xmlquot;);
foreach ($Customers->Customer as $customer) {
foreach ($Customers->Customer as $customer) {
print quot;$customer->Company<br>quot;;
print quot;$customer->Company<br>quot;;
} ?>
} ?>

Easy Extensions - Web Services
This example uses two web services
• One to obtain the price of a stock in US$
• The other to obtain the current US$ -> Cdn$ exchange rate
All you need to know is the name of the method
• All the underlying work is done for you
<?php
<?php
$QuoteClient = new SoapClient(
$QuoteClient = new SoapClient(
quot;http://services.xmethods.net/soap/urn:xmethods-delayedquotes.wsdlquot;);
quot;http://services.xmethods.net/soap/urn:xmethods-delayedquotes.wsdlquot;);
$CurrencyClient = new SoapClient(
$CurrencyClient = new SoapClient(
quot;http://www.xmethods.net/sd/2001/CurrencyExchangeService.wsdlquot;);
quot;http://www.xmethods.net/sd/2001/CurrencyExchangeService.wsdlquot;);
$IBM_Price = $QuoteClient->getQuote(quot;ibmquot;);
$IBM_Price = $QuoteClient->getQuote(quot;ibmquot;);
$US_Cdn_Rate = $CurrencyClient->getRate(quot;usaquot;, quot;canadaquot;);
$US_Cdn_Rate = $CurrencyClient->getRate(quot;usaquot;, quot;canadaquot;);
print(quot;IBM stock price is $$IBM_Price - that is $quot;
print(quot;IBM stock price is $$IBM_Price - that is $quot;
. ($IBM_Price * $US_Cdn_Rate) . quot; in Cdn$quot;);
. ($IBM_Price * $US_Cdn_Rate) . quot; in Cdn$quot;);
?>
?>

Easy Extensions - Web Services
This example uses one of the Google web services
• The spelling suggestion
The Google related logic is all on this page
• The next page simply shows the input form

<?php
<?php
if (isset($_POST['submit'])) {
if (isset($_POST['submit'])) {
$input = $_POST['input'];
$input = $_POST['input'];
$signature = quot;oJ+6HjxQFHKudrUwGI99RrEjLmQ5jrv1quot;;
$signature = quot;oJ+6HjxQFHKudrUwGI99RrEjLmQ5jrv1quot;;
$google = new SoapClient(quot;GoogleSearch.wsdlquot;);
$google = new SoapClient(quot;GoogleSearch.wsdlquot;);
$response = $google->doSpellingSuggestion($signature, $input);
$response = $google->doSpellingSuggestion($signature, $input);
If (!$response) $response = quot;Google hasn't a clue what you mean!quot;;
If (!$response) $response = quot;Google hasn't a clue what you mean!quot;;
} else { // This is just a form request so set field defaults
} else { // This is just a form request so set field defaults
$input = '';
$input = '';
$response = '';
$response = '';
}
}
?>
?>

Easy Extensions - Google (contd)
It is possible to do this in RPG using Scott Klement's HTTPAPI
• Or one of the other libraries
But the amount of code required is substantially greater

Business Application Framework
ATK has an interesting approach to Frameworks
• It focuses on business applications www.atk-framework.com
There is now an i5 specific version (i.e. DB2 enabled)
• But the web site is only in Dutch at present (www.i7.nl)
Ivo Jansch is presenting on the topic on Thursday
• quot;PHP in the Enterprisequot;

Using Native Record Level I/O
Dynamically accessing fields just cannot be done in RPG

// Get input data
// Get input data
$dbfile = $_POST['tbl'];
$dbfile = $_POST['tbl'];
$dblib = $_POST['lib'];
$dblib = $_POST['lib'];
if ($dbfile == '') $dbfile = quot;JONSDEMOSquot;;
if ($dbfile == '') $dbfile = quot;JONSDEMOSquot;;
if ($dblib == '') $dblib = quot;CUSTOMERSquot;;
if ($dblib == '') $dblib = quot;CUSTOMERSquot;;
$conn = i5_connect(quot;localhostquot;, quot;PARTNER400quot;, quot;PASSWORDquot;);
$conn = i5_connect(quot;localhostquot;, quot;PARTNER400quot;, quot;PASSWORDquot;);
// Open the file
// Open the file
$file = i5_open(quot;$dblib/$dbfilequot;, I5_OPEN_READ | I5_OPEN_SHRRD);
$file = i5_open(quot;$dblib/$dbfilequot;, I5_OPEN_READ | I5_OPEN_SHRRD);
if (!$file)
if (!$file)
die(quot;Error while attempting to open file mode=READ $i5_error()quot;);
die(quot;Error while attempting to open file mode=READ $i5_error()quot;);
// Print header row using field names
// Print header row using field names
$fields = i5_list_fields($file);// returns an array
$fields = i5_list_fields($file);// returns an array
print quot;<table border=1 cellpadding=3><tr bgcolor=#CCCCCC>quot;;
print quot;<table border=1 cellpadding=3><tr bgcolor=#CCCCCC>quot;;
// Parse the array
// Parse the array
foreach ($fields as $value)
foreach ($fields as $value)
{ print quot;<th>$value</th>quot;;
{ print quot;<th>$value</th>quot;;
}
}

Using Native Record Level I/O (cont.)
This works beautifully and doesn't annoy the SQL phobic!
// Print records
// Print records
$rec = i5_fetch_row($file, I5_READ_FIRST); // get array
$rec = i5_fetch_row($file, I5_READ_FIRST); // get array
while ($rec) // while there is a record...
while ($rec) // while there is a record...
{
{
?>
?>


<tr>
<tr>
<td><?php echo $rec[0]; ?></td>
</tr>
</tr>
<?php
<?php
$rec = i5_fetch_row($file, I5_READ_NEXT);
$rec = i5_fetch_row($file, I5_READ_NEXT);
} // loop
} // loop
print quot;</table>quot;;// finish off the table
print quot;</table>quot;;// finish off the table
?>
?>

i5 Function Sample - WRKSPLF
Originally released via the i5 Zend Core forum
• Find it by Googling with quot;php wrksplf site:zend.comquot;
Simple simulation of WRKSPLF built with i5 APIs
• Adds the ability to email or convert to PDF a spool file entry
The basic process it uses is:
• i5_connect( ) to connect
• i5_spool_list( ) to build list of spool files for the requested user
• i5_spool_list_read( ) to read the entries in the spool queue
• i5_spool_list_close( ) to close the spool link
• i5_close( ) to close the connection

If a spool file is selected for display:
• i5_spool_get_data( ) retrieves the spool records

Using RPG programs in new ways
The latest option - Zend 5250 Bridge
• A new approach for putting Green-screen applications to work in new ways
- For example as Web Services
- In a new quot;Web Facedquot; role
- Via Portals and Mash Ups
What is the quot;Bridgequot;
• How do you get it
• Technical Overview of components
The Bridge Demonstration Programs
• Green Screen Emulator
• Simple Web Interface
• AJAX style Web Interface
A brief example of the basic procedural APIs
• A different kind of 5250 Programming!
The Bridge is a Toolkit of possibilities
• Not a Silver Bullet quot;Solutionquot;
• Where might the future take us?

What is the quot;Bridgequot;
Three sets of APIs that allow a PHP script to drive a 5250 session
• Tow sets of APIs
- Object Oriented
- Procedural - these are the ones we will be focusing on
Multiple 5250 sessions can be connected to a single script
• So you could combine the data from several green screen
applications in a single browser window!
• You could also include data from another system's 5250 application
by using a Telnet connection
Bridge is available as part of Zend Platform
• Or as a quot;sandboxquot; single session version in a unlicensed version of
Platform (i.e. One for which the trial period has expired)

Product Advantages
Doesn't require WebSphere Application Server
• So CPW requirements are lower
No 5250 workload
• Use batch for green screen programs instead of interactive
Easy to install
• No application source required – works on display file objects
No charge for one connection
• Play in the sandbox until you can convince the boss to purchase
Modernize the application
• Using AJAX and other advanced web based technologies
Telnet enabled
• Can be used to telnet to other systems and blend results into a single
interface

Technical Overview
Supplied as a PHP library
• Contains a set of PHP functions/classes to access 5250 data
• Includes a number of demonstration programs
Allows you to run any 5250 applications under PHP control
• Utilizes IBM's WebFacing server
• Part of i5/OS TCP/IP
All screen data available ...
• Input and Output fields, positions and attributes

var_dump($inpfields);

print quot;nn<h3>Var_Dump of $outfields</h3>nnquot;;

var_dump($outfields);

zend_5250_disconnect($bridge);
?>

Display from Simple Bridge Demo
Each field on the screen is returned as an array element:
• Each element is in turn an array containing:
- Field id, Position (Row and Column), Length, Value, Color, type, etc.

Extract From Zend's Basic Subfile Demo
<?php
$status = zend_5250_get_output_field_value($response, 15);
if ($status == 1) {
echo quot;User is active<br />nquot;;
} elseif ($status == 2) {
echo quot;User is inactive<br />nquot;; }
?>
Serial number: <?php echo zend_5250_get_output_field_value($response, 11); ?>

echo quot;Preffered language: $lang<br />nquot;;
?>

Early Lessons Learned
Input and Output seem backwards
• quot;Inputquot; is the data you send to the 5250 application
- What you receive as input from the browser you will send on as input to
the 5250 application
• quot;Outputquot; is what you receive from the 5250 application
- You may or may not pass it on as-is to the browser user
Remember that the 5250 application won't directly see the input
• Your script must pass it on
You need to be able to identify screen layouts in some way
• Or you won't have a clue which screen is quot;talkingquot; to you
• The data from the bridge API does not include any format information
- You get the whole screen content - regardless of which format originated it

Early Lessons Learned (contd.)
Additional tools to determine field Id numbers are needed
• Latest modification to Zend's 5250 demo screen is helpful
• I am looking at the possibility of using a DSPFFD Outfile
- Build a database associated with each screen that uses row/column
coordinates to associates field names and the sequence identifier
¨ Subfiles and overlapping fields are a nuisance
- Result could be queried to map data to field name in script
- Using Outfile because corresponding API is really ugly
• Until there are more tools var_dump( ) and print_r( ) are your friends
Large scale projects are not for the faint hearted
• If we learnt nothing else from the early days of WebFacing ...
Remember that you will have to adapt to buffer layout changes
• But level checks should protect you from harm!

Procedural Bridge Functions (1)
zend_5250_open()
• Starts a session for the provided job id

zend_5250_connect()
• Creates a connection to the 5250 bridge using user name, password etc.

zend_5250_is_connected()
• Returns true if bridge is already connected

zend_5250_set_input_field()
• Sets data into an input field
- I.e It does the keyboard entry!

zend_5250_submit()
• Sends request to the 5250 bridge with a key (Enter, F keys, page up, etc.)
• Call after all input field values have been set

zend_5250_disconnect()
• Disconnects the 5250 bridge

zend_5250_set_focused_field()
• Sets the focus of the page to a specific field

zend_5250_get_focused_field()
• Returns the field currently in focus

zend_5250_get_input_fields()
and zend_5250_get_output_fields()
• Returns all input or output fields available

zend_5250_get_input_field()
and zend_5250_get_output_field()
• Returns a specific input or output field by ID

zend_5250_get_input_fields_count()
and zend_5250_get_output_fields_count()
• Returns the count of input or output fields available

zend_5250_get_application_error()

zend_5250_get_screen_size()
• Returns the size of the screen (width x height)

zend_5250_get_color_palette()
• Returns an array containing the i5 5250 Bridge color palette

Where Might The Future Take Us?
Think of Bridge is a quot;Toolkit of Possibilitiesquot;
• You could experiment with a web front end to an existing application
• Combine multiple applications into a single view
- Or subset the functionality of an application as in the subfile demo
• Use a portion of a 5250 application as a web service
• Build a different kind of 5250 application
- One that was never intended to drive a green screen!
- It certainly simplifies session persistence issues
What about tool builders?
• Zend and other parties may use the toolkit as a foundation for new
web enablement tools
- Perhaps an Open-Source project?
• Perhaps a starting point for a new web enabled RPG

Questions - Thoughts - Lunch ?

There will be tables at lunch for quot;iquot; folks to
