Function If() | IIf() Foundation
Returns the result of an expression dependent on a logical expression.
If( <lCondition>, <ExprTrue>, <ExprFalse>) --> xValue IIf(<lCondition>, <ExprTrue>, <ExprFalse>) --> xValue
When <lCondition> returns the value .T. (true), the return value of If() is the value of <ExprTrue>, otherwise it is the value of <ExprFalse>. The data type of the return value is the same as the type of the selected partial expression.
The function If() first evaluates the logical expression <lCondition>. Whether <lCondition> provides the value .T. or .F., a second expression is evaluated and the value of this expression is the return value of If(). This function is one of the most efficient and versatile Xbase++ functions. Using it, logical expressions can be converted to any other data type. The function can be written as If() or IIf().
