open:

Synopsis: open a file for read/write operations.

Syntax:	open ( FILENAME, MODE )
	open ( FILENAME, MODE, BUFFSIZE )

Description:

	Open will open a file  or a pipe for read or write
	operations. Open allows the user to specify the mode of
	operation, and optionally a buffer-size for I/O. The "normal"
	UNIX modes are:

	MODE:	"r"	read access
		"w"	write access
		"a"	append: open for writing at end of file, or
			create for writing

	BUFFSIZE:	Buffersize is specified in bytes. If BUFFSIZE
			is not specified the system defaults are used.

	Other operating systems may have different mode keys. Look at
	the API documentation for fopen() on your system to find what
	mode values are acceptable.
