Hi I wish anyone could help me out with ILLUSTRATIVE EXAMPLES for the encodig of Basic PER Aligned Variant for the types mentioned below. I've already consulted 2 books by Prof. John Larmouth and Dubuisson. ILLUSTRATIVE EXAMPLES with fictitious values for all these types will go a long way in comprehending these rules for encoding and would surely prove more pragmatic. 1. Length field 2. BOOLEAN 3. NULL 4. INTEGER 5. ENUMERATED 6. BIT STRING 7. OCTET STRING 8. OID 9. CHOICE 10. SEQUENCE and SEQUENCE OF Regards Zainul.
