SYSTEM INTRINSIC Statement
Calling MPE/iX intrinsics in HP FORTRAN 77/iX is usually identical to
calling MPE V intrinsics in HP FORTRAN 77/V.
* If your program uses system intrinsics that have been redefined in
MPE/iX (such as MYCOMMAND or CREATEPROCESS), make the appropriate
changes in calling methods. The usual reason an intrinsic is
redefined is that the MPE V version uses an address stored in a
16-bit variable or array element. Addresses are at least 32 bits
in MPE/iX. Because the FORTRAN 77/iX compiler does not know which
intrinsics have been redefined, it does not produce a warning when
one is used. See the MPE/iX Intrinsics Reference Manual, the
Programmer's Skills Migration Guide, and the Application Migration
Guide for the system intrinsics that are changed on MPE/iX.
Migration tools such as the Object Code Scanner and the Runtime
Event Logging Tool will also assist in identifying changed
intrinsics.
