in reply to Perl newbie question.

You could try to split your parameter and access the number of elements ... something like this:

    my @nr = split (/\s+/, $_[0]);
    print ($#nr+1, " params \n");

However you might want to do some fine-tuning ... the code above won't work correctly for parameters starting with whitespaces

HTH, Rata

update: or as an one-liner: print (scalar(split (/\s+/, $_[0])), " params \n");

    We can get the number of elements by simply assigning the return value of split into a scalar variable.

    Example 
    $str="1:3:4:5";
my $num=split(':',$str);
print "Num:$num";

    $num will contain '4'.
