Testing condition tokens for equality

To determine whether two condition tokens are equal (that is, the same instance or occurrence of the condition token), you must compare all 12 bytes of each condition token with each other. The last 4 bytes can change from instance to instance of a given condition.

The only way to test condition tokens for equality is to compare the value returned in fc with another condition token that has either been returned from a call to a service, or that you have coded as a 12-byte condition token in your routine. Symbolic feedback codes are used to test for equivalence; they are not useful in testing for equality because they represent only the first 8 bytes of the condition token.
