MPE/iX Intrinsics Reference Manual (32650-90875)

Chapter 2 31
Intrinsic Use
Additional Capabilities Required
• If the routine should always run in privileged mode, use the execution-privilege option
of the appropriate compiler and designate the execution level as 2. (Refer to your
programming language reference manual for more details.)
• If the routine requires privileged mode only on a selective basis, it is safer to obtain an
execution level of 2 only where necessary. To do this, invoke the GETPRIVMODE intrinsic.
CAUTION The normal checks and limitations that apply to standard users are bypassed
in privileged mode. A privileged mode program can destroy file integrity and
the operating system software. Hewlett-Packard will investigate and attempt
to resolve problems resulting from the use of privileged mode code. This
service, which is not provided under the standard service contract, is
available on a time and materials billing basis. Hewlett-Packard will not
support, correct, or attend to any modification of the operating system
software.
PS Capability
Programmatic sessions (PS) capability allows programmatic creation of sessions on any
terminal on the system.
