A user can only store commands in his own library. But he can GRANT other users the explicit call privilege for his commands and REVOKE it again from them.
To grant the PUBLIC privilege means to implicitly grant all ADABAS users the call privilege for a command.
The (implicit or explicit) call privilege allows all other users to call and to COPY a command. If the explicit privilege is revoked, the implicit privilege - if granted - is still valid.
When calling another user's command, the command name must be qualified with the owner's name. In MENU mode, it is sufficient to enter the number of the command in order to start it.
