This section describes the transformation of SEQUENCE data types. The SET data type is analogous to the SEQUENCE and so bears no extra discussion. As described in previous sections, the SEQUENCE OF and SET OF types are likewise equivalent.

The only significant difference between SEQUENCE and SET is that elements may be encoded in any order in a SET. ASN2CSV will order SET elements in the order they appear in the specification.

The SEQUENCEs considered in this section contain only simple types to simplify the collection of header data. Other cases are considered in the next sections.

Take, for example, the following SEQUENCE specification:

   S ::= SEQUENCE {
      i      INTEGER
      s      UTF8String,
      b      BIT STRING
   }        
         

Each element of the SEQUENCE will be represented by an item in the output CSV file as follows:

   i,s,b
