LISTBC command

Use the LISTBC command to display notices and mail. Notices are messages from the operator intended for all users to view. Mail is messages from another user or program to a particular user. By default, notices and mail are stored in the broadcast data set, SYS1.BRODCAST. However, your installation may use user logs. If so, mail is stored in and retrieved from individual user logs. Notices are still stored in and retrieved from the broadcast data set.

If your installation uses security labels and security checking and for SEND and LISTBC processing, MAIL messages are handled differently. When you enter the LISTBC command, LISTBC checks the security label on each MAIL message in your user log and compares it to your current security label (the security label you are logged on with). If your current security label is equal to or greater than the message's security label, the message is displayed. If your current security label is less than the message's security label, one of the following occurs:

If you are authorized to log on with a security label that is equal to or greater than the message's security label, you receive a message stating that there is a message in your user log that you cannot view at your current security label. Log off and log on at a greater security label and issue LISTBC again.
If you are not authorized to log on with a security label that is equal to or greater than the message's security label, the message is deleted and you do not receive notification that it was sent.

Note: For a list of the security labels you are allowed to log on with, use the RACF® command SEARCH CLASS(SECLABEL).
