TRANSFER$

Field of Application

Function executing a transfer from source to destination as speciﬁ ed by

a TRANSFERSET statement.

Syntax TRANSFER$(<nexp>)

<nexp> is the character time-out in ticks (10 milliseconds).

Remarks

The TRANSFER$ function executes the transfer from source to destination

as speciﬁ ed by the TRANSFERSET statement. It also checks the transfer and

breaks it if no character has been transmitted before the speciﬁ ed time-out has

expired or if any break character, as speciﬁ ed by the break character string

in the TRANSFERSET statement, is encountered.

If the transmission was interrupted because a character in the break set was

encountered, that character will be returned.

If the transmission was interrupted because of a time-out error, an empty

string will be returned.

If the transmission was interrupted because of the reception of a character

on any other communication channel than the source (as speciﬁ ed by

TRANSFERSET statement), an empty string will be returned.

Example

The transfer will be executed by the TRANSFER$ function in line 60 and

possible interruptions will be indicated by a break character or empty

string ("") in the string variable C$.
