The UNLICENSEDMSG parameter controls the issuance of the WER903I message. The absence of the UNLICENSEDMSG parameter or of the PARMS control statement in its entirety for a particular machine will cause the default (ON) to be put into effect. Note that the third line of the MFX header, which contains license information, is not written when WER903I is issued for MFX, since there is no valid key. This header line will still be suppressed even if the WER903I message has been suppressed.
When the WER903I message is written as a WTO, it will be written several times a day. The system will hold the message until it is deleted by the operator.
