help with perl while loop

Can anyone tell me why this program won't kick out when the time gets beyond time in the loop?

sub showtime

if ((! $military) && ($hour > 12)) {$hour-=12;}
$format =~ s/SS/$sec/g;
$format =~ s/HH/$hour/g;
$format =~ s/MM/$min/g;
return $format;
printf &showtime("The Time is Now HHMM\n",1);
while ($showtime le 2345)
while ($x==0 )
if (-e $legrun)
sleep 10;

As far as I can see the variable $legrun appears only once in your script, so the statement:

if ( -e $legrun) {

will never be true. You should define the filename before you check for its existance.

I figured it out, it was actually because I was not formatting showtime

while (&showtime(HHMM, 1) < 1422)
