- Transmission direction
Example:
XFILE "d2.dat","R"
"filename"
cannot be omitted even in file reception.
- Serial number
Example:
XFILE "d2.dat","S"
A serial number immediately follows a text control character heading each trans-
mission block. It is a 5-digit decimal number. When it is less than five digits, the
upper digits having no value are filled with zeros.
- Horizontal parity checking (BCC)
Example:
XFILE "d2.dat","P"
A block check character (BCC) immediately follows a terminator of each trans-
mission block. The horizontal parity checking checks all bits except for headers
(SOH and STX).
- Transmission monitoring
Example:
XFILE "d2.dat","M"
A serial number will appear in the 5-digit decimal format at the current cursor
position before execution of the
XFILE statement.
- Handling of trailing space codes in a data field during file transmission
Example:
XFILE "d2.dat","T"
Each of space codes placed in the tail of a data field will be handled as 20h in file
reception.
