Mode is the sum of any of the following constants: | Constant | Description | | fileOpenRead | Open file for reading | | fileOpenWrite | Open file for writing | | fileOpenAppend | Open and set write position to EOF | | fileOpenTrunc | Trunc file if opened file existed before | | fileOpenOld | The file ought to exist (don't combine this with fileOpenNew). | | fileOpenNew | The file must not exist (don't combine this with fileOpenOld) | | fileOpenBinary | Open in binary mode. By default files are opened in text mode where EOL is represented by a LF only.

var fh = fileOpen('address.dbf',
fileOpenRead+
fileOpenWrite+
