Tell Me It's True

The typical method of validating multiple expressions is to string together a series of If statements separated with an equal number of And statements. Shorten that process by passing one or more comma-delimited equations to return a True or False result:

 
Function IsTrue(ParamArray paOptions()) As Boolean
	Dim lLoop As Long

	IsTrue = True
	For lLoop = LBound(paOptions) To UBound(paOptions)
		IsTrue = IsTrue And paOptions(lLoop)
		If paOptions(lLoop) = False Then Exit For
	Next lLoop
End Function
