WEAK_GLOBAL

 The WEAK_GLOBAL attribute specifies that  an  object  is  linked
 only  when it is specifically included in the linking operation.
 To resolve a weak reference, the linker searches only the  named
 input  modules.   You  can specify an identifier to indicate the
 name by which the corresponding object is known to the linker.


 Syntax:

    [WEAK_GLOBAL]

 or,


    [WEAK_GLOBAL(identifier)]

 or,

    [WEAK_GLOBAL('string_literal')]

 The 'identifier' is the name of the  identifier  passed  to  the
 linker.  If you omit the identifier, the name of the variable is
 used.

 The 'string-literal' passes a specified string  literal  to  the
 linker unmodified.

 See the "HP Pascal Language Reference Manual" for  the  complete
 description of using the WEAK_GLOBAL attribute.
