mnemonic-name
Must be associated with an external switch, the status of which can be altered.

For Format 3 each mnemonic-name must be associated with an external switch, the status of which can be altered. The only external switches allowed are the UPSI switches, UPSI-0 through UPSI-7.

The status of each external switch associated with the specified mnemonic-name is modified such that the truth value resultant from evaluation of a condition-name associated with that switch will reflect an on status if the ON phrase is specified, or an off status if the OFF phrase is specified.
