Re: Help with multi-dimensional arrays (list of lists)

Hi,

in your code,

push @biu_yz, [ @biu_z ];
[download]

or similar pushes, you are pushing the reference. i.e. the operator [ ] will create an array, with same contents as that of @biu_z and return a reference to the new array. (see Anonymous Arrays)
When you try to access the value by

$biu[$i][4][$k] = $u25;
[download]

you need to use '->' operator to derefer it. try

$biu->[$i][4][$k] = $u25;
[download]

Cheers !

Sorry, but that's completely off base. The elements of `@biu` contain references, so you could do `$biu[$i]->[4]->[$k]` [download] but `->` is optional between indexes, so the following are all fine `$biu[$i]->[4]->[$k] $biu[$i]->[4][$k] $biu[$i][4]->[$k] $biu[$i][4][$k]` [download] `$biu->[$i][4][$k]` dereferences the reference in `$biu`, but there's no such variable in the program.
