( [id://3333]=superdoc: print w/replies, xml ) Need Help??
I prefer to call a "receiving" variable what it really is, so in subroutine BAR, I would do this:
sub BAR { my $arrayref = shift; #This will receive the array *reference* from + FOO ### Then, I can refer to specific elements of the ### array using the arrayref: my $first_element = $arrayref->[0]; ### or by turning the arrayref back into an array: my @bar_array = @{$arrayref}; my $1st_element = $bar_array[0]; #code here }
Remember, FOO is passing an array *reference* to BAR, so BAR receives an array *reference* - just my preference for clarity to include "ref" in the name of the variable so it's easy to tell what the variable contains. HTH.
