Before this a whole bunch of processing has been done, either:

A username/login has been entered and checked and a checkval generated and 
A cookie has been read and its value checked in the database
If everything is OK, then $REaderOK is set true (1). No output has been 
sent to the browser

Now this is encountered ...
if( $ReaderOK == 1 )
       echo "<a href = \"$PHP_SELF?cLangCode=$cLangCode\">" . 
$ErrorAndReturnMsg ."</a> </center>";

This is just about the end of all the logic stuff, and now the display 
portion of the page runs.
Note that in the else part of the code fragment, that the normal part of 
the display code is never reached because the page
is calling itself with with an error message to the user. If everything is 
ok, the user is sent back to the page ($origin) which called the logon 
script. That value was set thusly:

<? session_start();
session_register( "origin" );
. //after some checking if the user is not logged on the logon script is 
called here
