SHOWLA outputs library attributes. LD defines the library and LI provides the desired information.
The current administration privilege settings and the initial values for member protection are output. Passwords are not output. However, the user is informed that a password is allocated.
The library size, the free 2-K pages, the library format and a UPAM protection indicator are output as well.
The function shows the allowable storage mode for library members and the indicators for the borrowing mechanism and for member access date recording.
