Description

if expr1 then expr2 else expr3 : x
if expr1 then expr2 else expr3 produces the outcome of expr2 if expr1 succeeds, otherwise the outcome of expr3. The else clause is optional.
 
Parameters
expr1
boolean expression that is tested.
expr2
expression to evaluate if expr1 is true or succeeds.
expr3
expression to evaluate if expr1 is false or fails.
returns
result of expr2 or expr3
