Chapter 14. Statement Reference
295
• A communications device file should be opened before execution of the XFILE
statement. (For the file opening, refer to the OPEN "COM:" statement.)
• The XFILE statement uses the interface specified by the OPEN "COM:" statement.
• A data file to be transmitted should be closed beforehand.
• To transfer a file by using the BHT-Ir protocol , set the BHT's ID to any of 1 to FFFFh.
Specifying zero (0) to the ID will result in a run-time error.
• Undefined letters, if specified in protocolspec, will be ignored. The specifications
below, therefore, produce the same operation. The last one of the timeout values goes
active.
"RSPMT1"
"R,S,P,M,T,1"
"r,s,p,m,t,1"
"ABCDEFGHIJKLMNOPQRSTUVXYZ1"
"2"
"3462"
"22"
• If you transmit a data file having the same name as that already used in the receiving
station:
- the newly transmitted file replaces the old one when the field structure is matched.
- a run-time error occurs when the field structure is not matched.
To receive a data file having the same name at the BHT but having a different
structure, therefore, it is necessary to delete that old file.
• Pressing the Clear key during file transmission aborts the execution of the XFILE
statement by issuing an EOT code and displays a run-time error.
