Perl has a term called foreach. it works like this:
foreach $element (@array){dostuff.....;}
foreach takes the first element of array, makes $element a reference to that value, and does the loop. it does the next location next, and so on until the array is done. example
@numbers=(1,2,3,4,5);
foreach $digit (@numbers){print "$digit\n";}
This prints:
1
2
3
4
5
