Re: Accessing references

Both answers given thus far are equivalent, the arrows between subindexes are optional — but not the arrow between the variable name and the first index! That arrow makes the distinction between a scalar, that is a hash/array ref (which needs the arrow), and a an actual array/hash variable.

Anyway, please do take a look at the excellent tutorial for references that on modern perls is part of the core distro, as well as online: perlreftut

If you want to access the hash associated with column_defs, you might do, e.g. `keys %{$VAR1->{'column_defs'}};`That is, wrap the hash reference in curlies and then treat it exactly as you would a hash variable name. Is that what you're asking? Have you been through `perldoc perlreftut`? The PerlMonk `tr///` Advocate	[reply] [d/l] [select]
