Re^2: delete array element from array ref

Another way to avoid holes would be to filter out the holes with something like

@{$listref} = grep { defined } @{$listref};

after performing the deletion. (Of course that assumes that undef isn't a valid value in the list.)

Better would be: `@{$listref} = grep {exists} @{$listref};` [download] Update: this is of course complete bolix as pointed out by tinita++. Perl reduces RSI - it saves typing	[reply] [d/l]

`@{$listref} = grep {exists} @{$listref};` maybe you meant: `@{$listref} = map { exists $listref->[$_] ? $listref->[$_] : () } 0 .. $#{$listref} ;` ? update: typo	[reply] [d/l] [select]
