// declare some simple procedures proc display(cArg) echo "display=" + cArg endproc proc show(cArg) echo "show=" + cArg endproc // create an object based on an anonymous class myobj = new object() // add some properties myobj["name"] = "barry" myobj["company"] = "recital" // now declare an anonymous method myobj["mymethod"] = display // call the method myobj.mymethod("hello world") // displays "display=hello world" // redeclare the method myobj["mymethod"] = show // call the method myobj.mymethod("hello world") // displays "show=hello world"Where this becomes particularly useful is when you have a procedure that calls anonymous methods in order to process data. This technique can be used to call anonymous procedures in your code.
proc processdata(oArg) oArg.mymethod(oArg.name) endproc proc show(cArg) echo "show=" + cArg endproc myobj = new object() myobj["name"] = "barry" myobj["mymethod"] = show processdata(myobj) // displays "show=barry"
The following example connects to a Recital ODBC datasource, executes a query then outputs all the results from the resultset.
<?php
$sql = "select country from customers limit 10";
$conn = odbc_connect('Recital ODBC test', '?', '?');
$rs = odbc_exec($conn, $sql);
odbc_result_all($rs);
odbc_close($conn);
?>
Output:
<table><tr><th>Country</th></tr>
<tr><td>Germany </td></tr>
<tr><td>Mexico </td></tr>
<tr><td>Mexico </td></tr>
<tr><td>UK </td></tr>
<tr><td>Sweden </td></tr>
<tr><td>Germany </td></tr>
<tr><td>France </td></tr>
<tr><td>Spain </td></tr>
<tr><td>France </td></tr>
<tr><td>Canada </td></tr>
</table>

Note: Use of ? for the username and password on the local server is dependent on DB_LOCAL_LOGIN being enabled.
APPEND FROM <table-name>Before when appending into a shared Recital table each new row was locked along with the table header, then unlocked after it was inserted. This operation has now been enhanced to lock the table once, complete inserting all the rows from the table and then unlock the table. The performance of this operation has been increased by using this method. All the database and table constraints are still enforced.
Specifying this seems to reslove the problem:
-Xmx512m -XX:MaxPermSize=512m
In this article Barry Mavin explains step by step how to setup a Linux HA (High Availability) cluster for the running of Recital applications on Redhat/Centos 5.3 although the general configuration should work for other linux versions with a few minor changes.
There's a nice article on IBM developerworks describing how to package software using RPM. You can read it here.

The goal of the SCPlugin project is to integrate Subversion into the Mac OS X Finder.
- Support for Subversion.
- Access to commonly used source control operations via contextual menu [screenshot]
- Dynamic icon badging for files under version control. Shows the status of your files visually. [ screenshot ]
