<nexp
1

for input).
<nexp
2
> is the number of the destination fi le (the fi le or device OPENed
for output or append).
<sexp> is a set of break characters.
<nexp
3
> optionally enables or disables break on any other channel
than the source:

<nexp> ≠ 0 Break enabled
Default: Standard I/O with no break characters.

Remarks
This statement sets up the transfer of data from a fi le or device OPENed for
input to another fi le or device OPENed for output or append. The transfer
will be interrupted if any character in a string of break characters,
specifi ed in this statement, is encountered (optionally on another specifi ed
channel). The actual transfer is executed by means of a TRANSFER$
function, that also returns the break character that has caused any
possible interruption.
Example In this example, the data transfer from a fi le in the current directory to
an external device connected to the communication port "uart1:" will
be interrupted as soon as a carriage return or a line feed character is
encountered in the fi le.
