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-

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.
