VMS Help PASCAL, Attributes, Visibility, GLOBAL  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The GLOBAL attribute provides a strong definition of a  variable
  or  routine so that other independently compiled units can refer
  to it.

  Syntax:

     [GLOBAL]

  or,

     [GLOBAL(idenifier)]

  or,

     [GLOBAL('string-literal')]

  The 'identifier' is the name of the  identifier  passed  to  the
  linker.   It  is passed in uppercase on OpenVMS systems.  If you
  omit the identifier, the name of the variable is used.

  The 'string-literal' is  a  specified  string  literal  that  is
  passed unmodified to the linker.

  See the  "Compaq  Pascal  Language  Reference  Manual"  for  the
  complete description of using the GLOBAL attribute.
