Variable length records

Does clover support variable length records.
For example,
the falways irst 5 bytes define field 1
the always next 10 bytes define field 2
the next 2 bytes always contain the length of the remaining fields which are comma delimited.

Unfortunately this functionality is not implemented so far. The best solving approach I see in a implementation of recorods with a tree structure. And this is of course sheduled in our feature plan.
