<P>This command provides for writing one record into a file that has an internal record structure. Depending on the file&#146;s attributes, the write operation may result in ANDing or ORing the bytes specified in the command with the values already in the file. For the example, we&#146;ll assume that the attributes are set for a one-time-write operation; that is, this will be the initial writing of data into this record of the file.

<P>This command provides for the reading of one primitive data object. In the context of this class of commands, a data object is one of two types of data structures: a BER-TLV structure or a SIMPLE-TLV structure. TLV means a <I>tag, length,</I> and <I>value</I> structure (that is, a structure where a tag field gives an identity to the structure, a length field gives a size [in bytes], and a value field contains the piece of information that is the reason for the existence of the structure).</P>
<P>In a SIMPLE-TLV data object, the tag field is a single byte containing a number that identifies the data object, the length field consists of 1 or 3 bytes in length (if 1 byte the length is 0 to 254 bytes, if three the length is 0 to 64K bytes), and the value field is a string of bytes of length given by the length field. A BER-TLV structure is defined by the ISO/IEC 8825 standard.</P>
