HP Prime Graphing NW280AAABA Ctlg menu, Function.CHECK1, UNCHECKDigit, Enter Sequence.UNCHECK2

	Example:
	With the Function app as the current app, CHECK(1) checks
	the Function app Symbolic view variable F1. The result is that
	F1(X) is drawn in the Plot view and has a column of function
	values in the Numeric view of the Function app. With another
	app as the current app, you would have to enter
	Function.CHECK(1).
UNCHECK	Un-Check. Un-checks—that is, deselects—the Symbolic view
	variable corresponding to Digit. Used primarily in
	programming to de-activate symbolic view definitions in apps.
	UNCHECK(Digit)
	Example:
	With the Sequence app as the current app, UNCHECK(2) un-
	checks the Sequence app Symbolic view variable U2. The
	result is that U2(N) is no longer drawn in Plot view and has
	no column of values in the Numeric view of the Sequence
	app. With another app as the current app, you would have to
	enter Sequence.UNCHECK(2).
ISCHECK	Test for check. Tests whether a Symbolic view variable is
	checked. Returns 1 if the variable is checked and 0 if it is not
	checked.
	ISCHECK(Digit)
	Example:
	With the Function app as the current app, ISCHECK(3)
	checks to see if F3(X) is checked in the Symbolic view of the
	Function app.
