LBR

All librarian service routine names are prefixed with "LBR$". To create a new library or use an existing library, the LBR$INI_CONTROL routine must be called to obtain a context number. This is passed to the other LBR$ routines and allows multiple libraries to be accessed without having to close one to open a new one. LBR$Open is then used to open a library file. LBR$Close is used to close a library file when you are finished with it. LBR$OUTPUT_HELP can be used to display help to the user and query him for more information, without the need to use LBR$INI_CONTROL, LBR$OPEN, or LBR$CLOSE.
