encoding String in Encoding of the file. Default encoding is iso-8859-1.
For a list of possible encodings see Charset Definitions .
length Integer out Length (in Bytes) of the line that has been read. On file end, length is 0.
line String out File content of the line that has been read. On file end, line is NULL.

The path and file name of the file you want to access can be given dynamically via input parameter name, or statically via the definitions of an alias.
