HP 48gII Graphing, 50g Graphing ARG, ARCHIVE

Access:	!°LPICT ARC				( °is the left-shift of the Nkey).
Flags:	Angle Mode (–17 and –18). The setting of flags –17 and –18 determine the interpretation of xθ1
	and xθ2 (degrees, radians, or grads).
Input/Output:
		Level 4/Argument 1		Level 3/Argument 2	Level 2/Argument 3	Level 1/Argument 4	Level 1/Item 1
			(x, y)	xradius	xθ1	xθ2	→
			{ #n,#m }	#nradius	xθ1	xθ2	→
Flags:	Angle Mode (–17 and –18)

ARCHIVE	Command
Type:
Description:	Archive HOME Command: Creates a backup copy of the HOME directory (that is, all variables),
	the user-key assignments, and the alarm catalog in the specified backup object (:nport:name) in RAM
	or flash ROM.
	The specified port number can be 0 through 3, where 3 is the SD card. (Port 3 only applies to the
	HP 50g and 49g+.) An error will result if there is not enough memory in the specified port to
	copy the HOME directory.
	If the backup object is “:IO:name”, then the copied directory is transmitted in binary via Kermit
	protocol through the current I/O port to the specified filename.
	To save flag settings, execute RCLF and store the resulting list in a variable.
Access:	!°MEMORYLARCHIVE				( °is the left-shift of the Nkey).
Flags:	I/O Device (–33), I/O Messages (–39), I/O Device for Wire (–78) if the argument is “:IO:name”.
Input/Output:
			Level 1/Argument 1			Level 1/Item 1
				:nport :name	→
				:IO :name	→

ARG	Function
Type:
Description:	Argument Function: Returns the (real) polar angle θ of a complex number (x, y).
	The polar angle θ is equal to:

•atan y/x for x ≥ 0

•atan y/x + π sign y for x < 0, Radians mode

•atan y/x + 180 sign y for x < 0, Degrees mode

•atan y/x + 200 sign y for x < 0, Grads mode

A real argument x is treated as the complex argument (x,0).

Access:	…Ë		(Ëis the right-shift of the /key).
Flags:	Angle mode (–17, –18)
Input/Output:
		Level 1/Argument 1		Level 1/Item 1
		(x, y)	→	θ
		'symb'	→	'ARG(symb)'
