The above will not set the fifth element of @array to 'A', however, if that is what you are trying to do. What will actually happens depends upon the state of @array when this statement is executed. The left-hand side of the assignment statement is a list, which will be created as the first part of the statement execution. The list will then be assigned to the array variable @array. The value of the fifth element of the list will be assigned from the current value of the fifth element of @array. If this is the first time @array has been assigned a value, then that element will be null. If, in addition, you have 'use strict;' and have not declared @array previous to this statement, you will get a compilation error ("Global symbol "@array" requires explicit package name at ..."). Do this instead: my @array = qw( A B C D X E F ); $array[4] = $array[0]; -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
