VMS Help DECset, Context File  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  A context file contains statements which assign values to the
  various attributes comprising a context.  This file may also contain
  comment lines and blank lines.

  A statement is used in the context file to assign a value to a
  particular context attribute.  A hyphen may be used in the last
  character position of a line to continue a statement on the
  following line.

  Several of the statements that may appear in a context file are
  similar to DCL commands; however, the syntax of these statements is
  more restrictive than that of DCL.

  Note that a context file is automatically generated when you save a
  context via the Environment Manager's graphical user interface.
