BEEP	Command
Type:
Description:	Beep Command: Sounds a tone at n hertz for x seconds.
	The frequency of the tone is subject to the resolution of the built-in tone generator. The
	minimum frequency is 1 Hz and the maximum frequency in 15000 Hz. An input that doesn’t
	round to an integer within this range will cause the BEEP command to be skipped. Durations
	greater than 1200 seconds are automatically changed to 1200 seconds.
Access:	!°LOUT LBEEP		( °is the left-shift of the Nkey).
Flags:	Error Beep (–56)
Input/Output:

BESTFIT	Command
Type:
Description:	Best-Fitting Model Command: Executes LR with each of the four curve fitting models, and
	selects the model yielding the largest correlation coefficient.

The selected model is stored as the fifth parameter in the reserved variable ΣPAR, and the associated regression coefficients, intercept and slope, are stored as the third and fourth parameters, respectively.

Access: …µBESTFIT

Input/Output: None

BIN

Type:	Command
Description:	Binary Mode Command: Selects binary base for binary integer operations. (The default base is
	decimal.)
	Binary integers require the prefix #. Binary integers entered and returned in binary base
	automatically show the suffix b. If the current base is not binary, binary numbers can still be
	entered by using the suffix b (the numbers are displayed in the current base, however).
	The current base does not affect the internal representation of binary integers as unsigned binary
	numbers.
Access:	…ÃBIN	( Ãis the right-shift of the 3key).

Flags: Binary Integer Wordsize (–5 through –10), Binary Integer Base (–11, –12)

Input/Output: None
