Thanks for the tip, merlyn, I have "refactored" my code as follows:

use strict;
use LWP::Simple;
use POSIX;


my $refresh = 1800;

{
&imagegrab;
sleep $refresh;
redo;
}




sub imagegrab     {
    my $base="http://radar.weather.gov/ridge/RadarImg/N0R/MTX_N0R_0.gi
+f";
    
    my $timestring = strftime( "%Y%m%d_%H%M%S", gmtime() );

    

    my $savefilename = "SLCRadar_".$timestring.".gif";
    my $status = getstore($base,$savefilename);
        print $status."\n" ;

        }

It does seem a cleaner way to handle this...
