millicode
millicode. The system’s lowest-level machine-dependent code, often coded in assembler
language. TNS/E millicode and TNS/R millicode are functionally similar to the
microcode on TNS systems. The system has several types of millicode, including
machine interrupt handlers, operating system primitives, routines implicitly called from
native-compiled code, emulators for TNS floating-point arithmetic, and emulators for
privileged-only or long-running TNS machine operations.
Open System Services (OSS). An open system environment available for interactive or
programmatic use with the HP NonStop operating system. Processes that run in the
OSS environment usually use the OSS application program interface. Interactive users
of the OSS environment usually use the OSS shell for their command interpreter.

documentation for the product revisions. An RVU also includes a set of documentation
for the overall RVU.
RELOAD. An HP Tandem Advanced Command Language (TACL) command to load the HP
NonStop operating system image from disk over the ServerNet fabrics into the memory
of the processor.
