Chapter 14. Statement Reference

332

• 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:" state-

ment.

• A data file to be transmitted should be closed beforehand.

• To transfer a file by using the BHT-Ir protocol or multilink 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 specifica-

tions 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"

"ABCDEFGHIJKLMNOPQRSTUVWXYZ1"

"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.
