Perl for breakfast @breakfast = ("sausage","bacon","eggs"); # List Context @b = @breakfast; print @b," ... a list \n"; # Scalar Context $c = @breakfast; print $c," ... a scalar \n"; # Double Quote Context $d = "@breakfast"; print $d," ... in double quotes \n"; __END__ Perl doesn't have arrays - it has lists which can do all the good things an array can do, and much much more. This piece of code is a reminder of how a Perl list can be referred to in different contexts ... giving you the contents, the contents with a space between each element, and a count of the number of elements in the list with the most subtle of syntax changes. Results when run: earth-wind-and-fire:~/aug04 grahamellis$ perl nugget sausagebaconeggs ... a list 3 ... a scalar sausage bacon eggs ... in double quotes earth-wind-and-fire:~/aug04 grahamellis$ (written 2004-08-25 06:53:10) Associated topics are indexed under P208 - Perl - Lists
