When accepting a parameter, you will need to know how the other side sends the parameter.
If your other side sends the parameter as a CGI parameter, like:
http://example.com/cgi-bin/myscript.pl?sso=212453261
then you can read that parameter using the CGI methods:
my $sso = $query->param('sso');
$sso = 0+ $sso; # convert to number, strip all leading zeroes
But note that the "current directory" may not be what you think it is. When running other programs, you should use the full path to them and all filenames:
#*********SYSTEM CALL **********
#script within a script both files in same path
#This is required because the main script runs with ActiveState Extend
+ed Perl v5.24.1
#Whereas cqperl runs with v5.16.1 (limited features), cannot use Activ
+eState for this one.
#*********SYSTEM CALL **********
system( "c:\\path\\to\\cqperl C:\\another\\path\\to\\NewLdapUser.pl $
+sso $firstName $lastName $email" );

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
