TRANSFERSET

Field of Application

Statement for entering setup for the TRANSFER$ function.

Syntax TRANSFERSET[#]<nexp

>,[#]<nexp

>,<sexp>[,<nexp

# optional number sign.

<nexp

> is the number of the source (the ﬁ le or device OPENed

for input).

<nexp

> 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

> optionally enables or disables break on any other channel

than the source:

<nexp> = 0 Break disabled

<nexp> ≠ 0 Break enabled

Default: Standard I/O with no break characters.

Break on any other channel enabled.

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.
