Probably the easiest way to do this is to create a library that contains your links, then to require the library in each program.
Putting it in its own library file (within a subroutine is a good idea), requiring the library, and invoking the subroutine after $usrname has been defined should do the trick.
Example:
code for links.pl
<BLOCKQUOTE><font size="1" face="Arial,Helvetica,sans serif">code:</font><HR>
######################
# links.pl
#
# Contains the links for navigation
# between programs to maintaining
# username.
#####################
# SUB NAVIGATION
#
# Usage: $whatever = navigation($username)
#
# Description: This subroutine will take
# the username that's passed to it and
# return the list of links with the username
# incorporated into the links.
sub navigation {
my $user = shift;
my $links = qq~
<a href="program1.cgi?usrname=$user>Program 1</a><BR>
<a href="program2.cgi?usrname=$user>Program 2</a><BR>
<a href="program3.cgi?usrname=$user>Program 3</a><BR>
~;
return $links;
}
1;
</pre><HR></BLOCKQUOTE>
Then, in each of your programs that will require the links, put:
<BLOCKQUOTE><font size="1" face="Arial,Helvetica,sans serif">code:</font><HR>
require "links.pl";
$username = $FORM{'usrname'};
#or however you get this info
my $navlinks = navigation($usrname);
print qq~ <TABLE><TR><TD>
$navlinks
</TD></TR></TABLE>~;
</pre><HR></BLOCKQUOTE>
Hope this helps.
