I don't think so. For your other problem I found code I sent yesterday - not sure it's correct but what I understood from your sample :

a=0.1
b=1.1
For i= 1 To 5
	p=(a+b)/2
	If _myFunc(b)*_myFunc(a) < 0
		b=p
	Else
		a=p
	Endif
	? p
	If Abs(b-a) <= 0
		? p
		Exit
	Endif
Endfor
? 'outmessage'

Function _myFunc
Lparameters tnValue
* F(x)=(cos x -2x -0.5)   in [0.1,1.1]
Return ( Cos(m.tnValue) - 2*m.tnValue  - 0.5 )
