Conditional statement in if/then/else form
Description
Evaluates input according to a conditional statement specified in an if-then-else form.
Arguments
if[symbol]
optional
The arguments for the if object start with a conditional statement that uses the same syntax as expr. The word follows the conditional statement, which is then followed by a message expression. After the message expression, there is an optional and a second message expression.
if evaluates the conditional expression, and if the result is non-zero, evaluates the message expression after the word . Otherwise, it evaluates the second message expression after the word if an message is provided.
then, else[symbol]
optional
Message expressions are similar to what you type into a message box.
$i1, $f1, $s1[symbol]
optional
You use
, , or instead of for replaceable arguments. The number of inlets is determined by how many different changeable arguments are typed in. The maximum number of inlets is 9.
send[symbol]
optional
out2[symbol]
optional
The keyword if object. If precedes a message expression, the result of the expression is sent out the right outlet instead of the left outlet.
