How to change code after register globals is off

[Tezread]

I have changed web hosts and the new host strictly switches off register globals and recommends I amend my code. I have looked at the manual http://uk.php.net/register_globals but I am confused as to how I cna adapt my code to suit.

for example:

include("connect.php");

// array of alphabet using the range() function: 
$array = range('A', 'Z'); 
$array[] = 'Quality'; 


// loop through the letters: 
foreach($array as $value) 
{ 
    echo '<a href="?page=dictionary&amp;letter=' . $value . '">' . strtoupper($value) . '</a> |' . "\n"; 
} 

// grab letter from URL 
if (isset($_GET['letter'])) 
{ 
    $letter = trim(strtolower($_GET['letter'])); 
} 
else { 
    $letter = 'a'; 
} 
?>
<br><br>
          <?php

if (isset($_GET['letter'])) { 
include("connect.php");

$course = mysql_real_escape_string($_GET['letter']); 
$sql = "SELECT jargonterm FROM jargon WHERE letter = '$letter'"; 

$result = mysql_query($sql) or die(mysql_error());  

//echo $result."=result<br>
//";  

while($row=mysql_fetch_array($result))  

{ // NOTE this one ABOVE the echo 
//echo "result found!"; 
//echo $row[0]; 

echo '<a href="jargon_complete_details.php?jargonterm='. urlencode($row[0]) .'">'. $row[0] .'</a><br><br>';  


} 
}
?>            &nbsp;</td>
        </tr>
        <tr>
          <td width="303" height="23">&nbsp;</td>
          <td width="396">&nbsp;</td>
        </tr>
        <tr>
          <td height="20" valign="top">            <?php 
if (isset($_GET['jargonterm'])) { 
include('connect.php'); 

$course = mysql_real_escape_string($_GET['jargonterm']); 
$res = "SELECT jargonterm, explanation  FROM jargon WHERE jargonterm = '$jargonterm'"; 
$result = mysql_query($res) or die(mysql_error()); 
if (mysql_num_rows($result) > 0) { 
while ($row = mysql_fetch_assoc($result)) { 

} ?>

this worked with register globals on but now i get the error:

Notice: Undefined variable: jargonterm in /var/www/vhosts/mindseyemidlands.co.uk/httpdocs/notts_quality/info_resource/jargon_complete_details.php on line 120

I tried $jargonterm = FALSE; but this resulted in the term not appearing at all with no error messages either

Change these two lines...

$course = mysql_real_escape_string($_GET['letter']);

$course = mysql_real_escape_string($_GET['jargonterm']);

...to...

$letter = mysql_real_escape_string($_GET['letter']);

$jargonterm = mysql_real_escape_string($_GET['jargonterm']);

thankyou nogdog- how about in this instance of this more complicated script:

$result = mysql_query($sql); 
// if we have rows, fetch them & prepopulate the form
if(mysql_num_rows($result) > 0) {
