The message the logical OR test passed appears because one of the conditions in the if
statement is true (y>200). Although the other two expressions evaluate to false, as long as
one condition evaluates to true, the if block is executed.
The following example demonstrates how using a function call as expression2 can lead to
unexpected results. If the expression on the left of the operator evaluates to true, that result is
returned without evaluating the expression on the right (the function fx2() is not called).
function fx1():Boolean {
trace("fx1 called");
return true;
}
function fx2():Boolean {
trace("fx2 called");
return true;
}
if (fx1() || fx2()) {
trace("IF statement entered");
}
/* The following is sent to the Output panel: /* The following is sent to
the log file: fx1 called IF statement entered */

Deprecated since Flash Player 5. This operator was deprecated in favor of the || (logical
OR) operator.
Evaluates condition1 and condition2, and if either expression is true, the whole expression
is true.
Operands
condition1 : Boolean - An expression that evaluates to true or false.
condition2 : Boolean - An expression that evaluates to true or false.
Returns
