|nOffset||(Long) Specifies the position of read value in the data block.
The read value must be inside the data block. The item is read either whole or not read at all.
>= 0 - Index (in bytes, zero-based index) in the data block.
-4 - The internal automatic position is used (see the AutoOffset property). It points behind the last read or written value.
This operation shifts the internal automatic position behind the read/written value.
If the items are read/written one by one then it is not necessary to define the position manually, but it is better to use this automated positioning.
|sFile||(String) The file name with the path.
If a full path is not entered, then it is completed relative to the application folder.
It is recommended to use the PROMOTIC path syntax - see PROMOTIC path to files and folders.
|nFileOffset||[optional] (Long) Specifies the position of written value in the binary file in bytes.
The 0 value (default) means writing from beginning of the file.
|nLength||[optional] (Long) Specifies the number of written bytes.
>=0 - The number (count) in bytes
-1 (default) - Writing all values up to the end of the data block.
-2 - Writing all values up to the end of the data block and then sets the end of the file.
