DevWriteLn

Writes a string to a device. If the device is free-format, the data is written to the device, followed by a newline character. If the device is record-based, a new record is appended to the device and the data is written to this record. The record pointer is then moved to the next record.

Syntax

DevWriteLn(hDev, sData)

hDev:

The device handle, returned from the DevOpen function. The device handle identifies the table where all data on the associated device is stored.

sData:

The data to write, as a string.

Return Value

0 (zero) if successful, otherwise an error is returned.
