Re: Re: Parameters, subs and the shift function

Abagail-II, what is the signifigance of the + in the shift statements? Why is this a good thing to do?

my @array1 = @{+shift};
my @array2 = @{+shift};

Run it under strict, and try it without the `+`. The error message you get will enlighten you. Abigail	[reply]

Ahh, thank you. I'm a little embarrassed. I never dereferenced a builtin like shift only user defined functions. `Global symbol "@shift" requires explicit package name at noname5.pl li +ne 5. Global symbol "@shift" requires explicit package name at noname5.pl li +ne 6. Execution of noname5.pl aborted due to compilation errors.` [download]	[reply] [d/l]
