       [, [External                 =>] EXTERNAL_SYMBOL]

       [, [First_Optional_Parameter =>] IDENTIFIER]);
     
     EXTERNAL_SYMBOL ::=
       IDENTIFIER
     | static_string_EXPRESSION
     
     PARAMETER_TYPES ::=
       null
     | TYPE_DESIGNATOR {, TYPE_DESIGNATOR}
     
     TYPE_DESIGNATOR ::=
       subtype_NAME
     | subtype_Name ' Access
     
     MECHANISM ::=
       MECHANISM_NAME
     | (MECHANISM_ASSOCIATION {, MECHANISM_ASSOCIATION})
     
     MECHANISM_ASSOCIATION ::=
       [formal_parameter_NAME =>] MECHANISM_NAME
     
     MECHANISM_NAME ::=
       Value
     | Reference
     | Descriptor [([Class =>] CLASS_NAME)]
     | Short_Descriptor [([Class =>] CLASS_NAME)]
     
     CLASS_NAME ::= ubs | ubsb | uba | s | sb | a | nca

This pragma is identical to Import_Function except that it applies to a procedure rather than a function and the parameters Result_Type and Result_Mechanism are not permitted.
