CR	Command
Type:
Description:	Carriage Right Command: Prints the contents, if any, of the printer buffer.
	When printing to the serial port (flag –34 set), CR sends to the printer a string that encodes the
	line termination method. The default termination method is carriagereturn/linefeed. The string is
	the fourth parameter in the reserved variable PRTPAR.
	When using the HP 82240B Infrared Printer (flag –34 clear), CR leaves the printhead on the right
	end of the just printed line.
Access:	…µCR
Flags:	I/O Device (–33), Printing Device (–34), DoubleSpa ced Printing (–37), I/O Device for Wire (–

CROSS	Command
Type:
Description:	Cross Product Command: CROSS returns the cross product C = A × B of vectors A and B.
	The arguments must be vectors having two or three elements, and need not have the same
	number of elements. (The calculator automatically converts a twoelement argument [ d1 d2 ] to a
	threeelement argument [ d1 d2 0 ].)
Access:	!´VECTOR CROSS		( ´is the leftshift of the Pkey).
Input/Output:
		Level 2/Argument 1 Level 1/Argument 2			Level 1/Item 1

CSWP	Command
Type:

Description: Column Swap Command: Swaps columns i and j of the argument matrix and returns the modified matrix, or swaps elements i and j of the argument vector and returns the modified vector.

Column numbers are rounded to the nearest integer. Vector arguments are treated as row vectors.
