	See the IF, CASE, IFERR, DO, and WHILE keyword entries for more information.
Access:	!°BRANCH IF/CASE/DO/WHILE END ( °is the leftshift of the Nkey).
Input/Output:	None

ENDSUB	Command
Type:
Description:	Ending Sublist Command: Provides a way to access the total number of sublists contained in the
	list used by DOSUBS.
	Returns an Undefined Local Name error if executed when DOSUBS is not active.
Access:	!°LIST PROCEDURES ENDSUB		( °is the leftshift of the Nkey).
Input/Output:	None
Example:	The following program subtracts the number of elements in a list from each element in the list
	« → a « a 1 « ENDSUB » » DOSUBS »

ENG	Command
Type:
Description:	Engineering Mode Command: Sets the number display format to engineering mode, which
	displays one to three digits to the left of the fraction mark (decimal point) and an exponent that is
	a multiple of three. The total number of significant digits displayed is n + 1.
	Engineering mode uses n + 1 significant digits, where 0 ≤ n ≤ 11. (Values for n outside this range
	are rounded up or down.) A number is displayed or printed as follows:
		(sign) mantissa E (sign) exponent
	where the mantissa is of the form (nn)n.(n…) (with up to 12 digits total) and the exponent has one
	to three digits.
	A number with an exponent of –499 is displayed automatically in scientific mode.
Access:	!& H FMT ENG
	!°LMODES FMT ENG		( °is the leftshift of the Nkey).
Input/Output:
		Level 1/Argument 1	Level 1/Item 1
		n	→
	The number
Example:		103.6 in Engineering mode with five significant digits (n=4) would appear as
	103.60E0. This same number with one significant digit (n=0) would appear as 100.E0.

EPSX0
Type:	Function
Description:	Replaces all coefficients in a polynomial that have an absolute value less than that held in the
	CASDIR variable EPS, with 0. The default value of EPS is 1E10, which can be changed by
	storing a new number in the variable EPS in the CASDIR directory; this must be less than 1.
Access:	Catalog, …µ
Input:	A polynomial.
Output:	The polynomial with conforming coefficients replaced with 0.
Flags:	Exact mode must be set (flag –105 clear).
	Numeric mode must not be set (flag –3 clear).
