Use (Byle)
Under the knife to identify the version rate of the exchange system. The length is 3 characters, and the structure is as shown in the figure below, where "version search" is represented by a 1-bit integer: "separator" is represented by an English semicolon, and "minor version number" is represented by a 1-bit integer. Version search

5.3 Machine code type
Identifies the sender's machine type, and is used to convert data formats between different models and different operating systems. The codes represent different meanings at the same time, such as
\1\CPL is the machine code type of the Imtel x36 series 2\CPT: is the machine code type of the PuwrPC series or AS/400 series\3\:CPt: is the machine code type of the Ss:em/asg series. The missing value of this bit is "[".
5.4 Total number of XIF bytes
Used for calculating the length of variable-length XIF. The length is 4 characters. A total of 32 1. The maximum representation range is 2% 1 Byte:
5-5 Address length
indicates the standard length of a single address. For the processing of non-standard length addresses, when the receiving address is multiple, the address lengths are split according to the address length.
5.6 Source address
indicates the address that the data must be sent to. It is not processed during the transmission between stations. The encoding of this code is based on the GA380 standard.
5 .7 The address of the last developed place
indicates the address of the station on which the code was sent. The abbreviation of this code is compiled according to the provisions of A381. 5. The address of the last day
indicates the address of the last month of the transmission. It can be a multiple-month address. The type of this segment is optional and its length is variable. The code 2
=TTKANKA:
is compiled according to the provisions of (A3). 5.9 The destination of this transmission
C4 381.22002
indicates the next station to be sent. The encoding of the segment code is based on the provisions of A330. 5.10 Transmission priority
indicates the transmission priority of the data to be sent. This character is represented by a character. The value range is 1~1. Among them, 1 indicates the lowest priority, 9 indicates the highest priority, and the default value is 1. 5.11 Exchange request flag
indicates whether the exchange request is required. It is a character long. The value range is 1 or 2. Among them, 1 indicates no request for reply, and 2 indicates request for reply. The default value is 1.
5.12 Transmission timeout
indicates that if the data is not successfully sent within the specified time, the sending activity of the data will be considered to be canceled. The calculation is in seconds. The length is 4 characters, with a total of 32 1s. The maximum value is 0. When the character is not 0, it indicates the transmission time limit, that is, permanent validity. The default value of this field is 2 hours.
5.13 Original data identifier length
indicates the length of the file to be sent. The length is 4 characters, with a total of 32 1s. The maximum value is 21 bytes (bytes).
5.14 Original validity period
indicates the name of the data to be sent. The receiving system stores the data in this file name. The length is character type and variable length. 5.15 Transmission data identifier length
indicates the length of the data to be transmitted. The length is 4 characters, which has 32 bits, and the range is 23 to 1 byte.
5.16 Transmission data identification
indicates the unique identification of data in the exchange system. This field type is optional and variable. 5.17 Data transmission time
indicates the time when the data enters the exchange system. It is expressed in year, month, day, hour, minute, and second. The length is 10 characters. The first 4 characters represent year, month, day, and the last 4 characters represent hour, minute, and second.
