Recital 10 introduced the ARRAY( ) functions. This function operates in the same way as the PHP ARRAY( ) function. It can be used to declare a dynamic or associative array and optionally initialize it with elements.

// declare an empty dynamic array
a = array()

// declare a simple dynamic array
a = array("barry", "recital", "boston")
foreach a as value
    echo value
endfor

// declare an associative array
a = array("name" => "barry", "company" => "recital", "location" => "boston")
echo "length of a is " + len(a)
foreach a as key => value
    echo "key=" + key + ", value=" + value
endfor

The SET RELATION Recital Navigational Data Command can be used to link two (or more) tables based on the master index key of the child table.  With a relation active, as you move through the parent table, the record pointer also moves in the child table, automatically selecting the first related record or moving to the end of file if no related record exists.    

open database southwind
// open child table
use order_details order orderid in 0
// open parent table
use orders order orderid in 0
set relation to orderid into order_details
do while not eof()
    ? orders.orderid, order_details.productid
    skip
enddo

The code above will display the productid from the first related record, but you will often want to display information from all the related records in the child or detail table as in an SQL Left Outer Join.

open database southwind
select orders.orderid, order_details.productid;
from orders left outer join order_details;
on orders.orderid = order_details.orderid

In this case, we can use a second nested DO WHILE loop, for example:

open database southwind
use order_details order orderid in 0
use orders order orderid in 0
set relation to orderid into order_details
do while not eof()
    // Display first or 0 child record
    ? orders.orderid, order_details.productid
    // Display any additional child records
    do while not eof(order_details)
        ? orders.orderid, order_details.productid
        skip in order_details
    enddo
    skip
enddo

Or we can use the SET SKIP command.  The SET SKIP command can be used with DISPLAY, LIST and REPORT and automatically skips through all the related records in the child table.

open database southwind
use order_details order orderid in 0
use orders order orderid in 0
set relation to orderid into order_details
set skip on
set skip to order_details
list orders.orderid, order_details.productid

LIST and DISPLAY offer a number of keyword options to allow you to configure the display output.  REPORT offers full column based report design.

Recital is a dynamic programming language with an integrated high performance database particularly well suited for the development and deployment of high transaction throughput applications.  Recital 10 further enhances Recital with extensive features and functionality to facilitate its use in fault tolerant high availability systems. Much of the development of Recital 10 was concentrated on performance optimizations and cluster aware functionality to provide an application platform that can be scaled as needed without any application changes. 

Key features of Recital 10 include:

• Cluster aware database engine that works transparently with drbd, heartbeat, glusterfs and samba
• High degree of fault tolerance with self healing indexes
• Massive performance improvements 
• Extensive internals overall and modernization with superior object-oriented capabilities
• Chronological data versioning with database timelines
• SmartQuery caching
• Database Administration Tools
• Code and Data Profiling
• Better integration with unix/linux command shell
• Incorporates a range of new built-in functions compatible with those in the PHP core libraries
• Built-in support for outputting data in HTML, XML, and JSON format
• Seamless SQL command integration into the Recital scripting language
• Much improved Microsoft FoxPRO language compatibility
• Numerous extensions and improvements (see below for details)
• Very large file support (2^63)

Recital provides the following additional benefits:

• Easy to Install and Deploy - Users can set up Recital in minutes enabling organizations to deliver new applications faster than other databases.
• Easy to Administer - Recital is a low administration database that eliminates the need for highly trained, skilled, and costly database administrators to maintain the database.
• High Performance - Superior database performance for the most demanding of OLTP applications. Additionally, Clustered Recital provides 99.999% availability.
• Embeddable Library - Recital Embedded Edition provides in-process data storage engine that delivers all the features of a traditional relational database but in a size which makes it ideally suited for ISVs/VARs who need a small footprint and easy to use toolkit.
• Platform Independence - Recital runs on Linux, Solaris, AIX, HP-UX, Windows, and Mac OS X giving organizations complete flexibility in delivering a solution on the platform of their choice.
