I am no expert on this, and not being able to find any example of ||=, I wrote this; #!/usr/bin/perl use strict; my $a = $a || 2; print "$a\n"; $a = 3; my $a = $a || 2; print "$a\n"; my $a = $a ||= 2; print "$a\n"; undef $a; my $a = $a ||= 2; print "$a\n"; So I come to the conclusion that || and ||= are the same, but in terms of precedence, || will have the higher precedence than ||= -- Owen -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
