If INLINE is specified, but DEC Fortran cannot generate inline code, it maps the call to the appropriate VMS Math Library or Digital Extended Math Library routine.
If NOINLINE is specified, no inline code is generated; references can only be mapped to the OpenVMS Math Library (unless NOMAPPED is in effect).
MAPPED
Controls whether the Basic BLAS routines can be mapped to the
appropriate OpenVMS Math Library or Digital Extended Math Library
routine, if the reference is not inlined or NOINLINE is in
effect.
If both NOINLINE and NOMAPPED are specified, DEC Fortran does not recognize BLAS routines as intrinsics. If INLINE and NOMAPPED are specified, references that are not expanded inline cause the unmapped external routine name to be called. For the Extended BLAS routines, the unmapped external routine name is always used if the reference is not expanded inline.
ALL
Same interpretation as (INLINE,MAPPED). This is the default.
NONE
Same interpretation as (NOINLINE,NOMAPPED).
