characters are all represented by quadruples beginning with
three zeros like {0,0,0,65} for the 'A' character. When
decoding a value for these strings the result is a list of
- quadruples, or integers when the value is an ASCII character.
- The following example shows how it works:</p>
- <p>In a file <c>PrimStrings.asn1</c> the type <c>BMP</c> is defined as
- <br></br>
-<c>BMP ::= BMPString</c> then using BER encoding (<c>ber</c>
- option)the input/output format will be:</p>
+ quadruples, or integers when the value is an ASCII character.</p>
