Parameters	Description
<exp1>	The expression to be checked.
<exp2>	Expression representing the range minimum.
<exp3>	Expression representing the range maximum.

The <exp1> must be equal to or more than <exp2> and equal to or less than <exp3> for BETWEEN() to return true (.T). If <exp1> is not within this range, BETWEEN() returns false (.F.).
