Re: @_ & @ARGV

in reply to @_ & @ARGV

@_ contains the arguments to the current (inner-most) subroutine, which is why the @_ in the inner subroutine is different from that of the outer subroutine. shift acts on @_ by default, which is why it gets the first argument to the inner-most function.

Strictly speaking,

my @list = @_; print @_, ' out return', "\n";

is the only content directly in sub formatlist, the rest is in an inner functio which has its own @_.

[Lady_Aleena]: james28909, you might want to look at the other two on my scratchpad.
[james28909]: after you send to a sub, you can check if it is array or ref ect with ref
[james28909]: check if it is a hash or an array ect with ref in one sub.
[james28909]: like all the subs calling get_data get_array get_ect, you could just use get_data. once you send the data to get_data, check if it is a hash or an array ect. and do functions for each, in one sub
[james28909]: that looks like it would be alot more work than just renaming the sub though lol
[Lady_Aleena]: james28909, did you even look at the subs?
[james28909]: yes
