Usually I have trouble getting up when my alarm goes off. Today, I'm
having a lot of trouble just trying to set it! I keep getting
syntax error in file e12 at line 4, next 2 tokens "alarm 60"
Execution aborted due to compilation errors.
Where is my mistake? It seems to me to be according to The Book.......

#!/usr/bin/perl
$SIG{'ALARM'} = 'sighandler';
# also tried alarm(60); , $n = alarm(60);, and $n = 60;alarm($n);
alarm 60 ;
for ($i=0;$i<200000;$i++) { $j = $i-1;}
print "complete \n";
exit(0);
sub sighandler {
local($sig) = @_;
print "caught it now! $sig\n";
exit(1);

The Book purports to document only version 4.0. alarm was a fairly late
addition to 3.0, so it's probably not in your installed version.
