The ones that are not ignored are the ones that are invalid; i.e., higher than the highest allowable number but also not equal to X'FF'. If your channel program has an invalid sector number, the ESS will fail your channel program with unit check - invalid parameter. If your number is valid, however, it would seem that the ESS will ignore it.
It seems to me that this is reasonable behaviour iff the default value is licit. EJ's recommendation would obviate all problems. Explicit, willful specification of a value greater than the largest licit value and less than x'ff' should be diagnosed.
