Save and reuse library list

when from the same menu run different applications -- you need to replace your library list with a new one, but later you want to use the old library list and the current library again.

Sometimes, however, you can't add or remove libraries from the library list. The CL Program LIBLIST can help you to save the current library and the library list into variables and restore them again when you need them. The CLP can be use as a called separate program or as a portion of an existing CL Program.
