<?php

function xyz_block($op='list', $delta=0, $edit = array())

{

    if( $op == 'list' ) {

             $block[0]['info'] = "Test";

                         

             

    } else if ( $op == 'view' ) {

            switch($delta) 

            {

                 case 0:

                         $block['subject'] =  "Test";

                         $block['content'] =  xyz_Services();

                         break;

            }

     }

                         

     return $block;

}

function xyz_Services()
