 X Note:  If you specify a suboption that is not applicable to the platform,

 X        the entire CALLINTERFACE directive is ignored for that platform.

 X        For example, if you specify >>CALLINT CDECL for an OS/2 program, it

 X        is ignored.


 X        For more information on which suboptions are in effect for multiple

 X        directive and compiler option specifications, see "Precedence of

 X        Sub Options" in topic 8.2.1.2.1.



 X SYSTEM

 X     Specifies that the system linkage convention of the platform is used

 X     as the call interface convention.


 X OPTLINK

 X     Specifies that the _Optlink calling convention as defined by C Set++

 X     is used as the call interface convention.


 X FAR16

 X     Specifies that the _FAR16_CDecl calling convention as defined by C

 X     Set++ is used as the call interface convention.


 X PASCAL16

 X     Specifies that the _FAR16_Pascal calling convention as defined by C

 X     Set++ is used as the call interface convention.


 X CDECL

 X     Specifies that the CDECL calling convention as defined by Microsoft

 X     Visual C++ is used as the call interface convention.


 X DESC, DESCRIPTOR

 X     Indicates that an argument descriptor is passed for each argument on a

 X     CALL statement.


 X NODESC, NODESCRIPTOR

 X     Indicates that no argument descriptors are passed for any arguments on

 X     a CALL statement.  NODESC/NODESCRIPTOR is the default.



 X Specify CALLINTERFACE only in the Procedure Division.


 X The positions of CALL statements relative to the >>CALLINTERFACE directive

 X are recognized following any processing of COPY and REPLACE statements.

 X For example, CALL statements and >>CALLINTERFACE statements in COPY text

 X are processed by the rules specified for the directive.
