Hello,
<< get_sabp_pdu_len(), that looks at the first few bytes of the message (using a routine to do so for ASN.1 PER)>>
Actually I was asking for some help in this regard only. How does it look at the first few bytes of the message? Where the procedure is mentioned (not asking in the code)?

Yes.

It does it by calling tcp_dissect_pdus() in its dissector routine, passing it a get_pdu_len routine, get_sabp_pdu_len(), that looks at the first few bytes of the message (using a routine to do so for ASN.1 PER) to determine the length.
See Anders's message for details.
