21.3 Creating User-Supplied Object Module Libraries
  You create a user-supplied object module library with the
  DCL command LIBRARY. Specify a library file specification
  as well as a list of the program modules you want to insert
  into the library. For example:
  $ BASIC MODULE1,MODULE2
  $ LIBRARY/CREATE TESTLIB1.OLB MODULE1.OBJ,MODULE2.OBJ

  In the previous example, the BASIC command creates ob-
  ject files from MODULE1.BAS and MODULE2.BAS. The
  LIBRARY command creates an object module library
  named TESTLIB1.OLB and inserts MODULE1.OBJ and
  MODULE2.OBJ into that library. See the OpenVMS DCL
  Dictionary for more information about the LIBRARY com-
  mand.
