upgrading?  :-)  v3.8 will get you dictionaries, though no "animation scope"
variables.

have a look at 'Filed()', another recent macro of mine.  you can read a range of
"records", or all. a range can be a single record, and you could use
'frame_number' to "index".  serialising a dictionary using 'Filed()' would be
straightforward too.
