Immediate If

Visual Basic programmers have a function at their disposal called IIf(), which is an abbreviation for Immediate If.

Example

result = IIf(2 + 2 = 5, "Correct", "Wrong")

The iif() function is sometimes more convenient than a full-blown if...then...else... control structure. Oddly enough, the function does not exist in VBScript.

Our PHP programmer friends have a superior equivalent, the ternary operator.

Example

$result = (2 + 2 = 5) ? 'Correct' : 'Wrong';

Unfortunately we can't recreate the ternary operator in ASP, but we can recreate the iif() function.

ASP

1. function IIf(expression, truecondition, falsecondition)
2.     if isNull(expression) then
3.         IIf = falseCondition
4.     elseif cbool(expression) then
5.         IIf = truecondition
6.     else
7.         IIf = falsecondition
8.     end if
9. end function
