Glossary-3
high PIN
users of the Guardian environment use the HP Tandem Advanced Command
Language (TACL) or another HP product’s command interpreter. Contrast with Open
System Services (OSS).
high PIN. A process identification number (PIN) in the range 256 or higher.
Home Terminal. )þ(1) The terminal from which a process is started. (2)þThe terminal from
which the ENFORM command is entered. (3)þThe terminal whose name is returned by
a call to the MYTERM procedure, or the name returned in the hometerm parameter of
the PROCESS_GETINFO_ procedure.
HP NonStop operating system. The operating system for HP NonStop systems.
HP NonStop Series (TNS). HP computers that support the HP NonStop operating system
and that are based on complex instruction-set computing (CISC) technology. TNS
processors implement the TNS instruction set. Contrast with HP NonStop Series/RISC
(TNS/R).
HP NonStop Series/RISC (TNS/R). HP computers that support the HP NonStop operating
system and that are based on reduced instruction-set computing (RISC) technology.
TNS/R processors implement the RISC instruction set and are upwardly compatible
with the TNS system-level architecture. TNS/R processors include the NSR-L and
NSR-N processors. Contrast with HP NonStop Series (TNS).
Lobug. A low-level debugger available to service providers.
low PIN. A process identification number (PIN) in the range 0 through 254.
memory-exact point. A location in an accelerated program at which the values in memory
(but not necessarily in the register stack) are the same as they would be if the program
were running on a TNS processor. Most source statement boundaries are memory-
exact points. Complex statements might contain several such points: at each function
call, privileged instruction, and embedded assignment. Contrast with register-exact
point.
memory manager. A system process that manages physical memory in a
processor module.
message system. A set of operating system procedures and data structures that handles
the mechanics of exchanging messages between processes.
millicode. RISC instructions that implement various TNS low-level functions such
as exception handling, real-time translation routines, and library routines that
implement the TNS instruction set. Millicode is functionally equivalent to
TNS microcode.
module. A physical grouping of procedures and data structures.
