TNS instructions
TNS instructions. Stack-oriented, 16-bit machine instructions defined as part of the TNS
environment. On TNS systems, TNS instructions are implemented by microcode; on
TNS/R systems, TNS instructions are implemented by millicode routines or by
translation to an equivalent sequence of RISC instructions. Contrast with “RISC
instructions.”
TNS mode. The operational environment in which TNS instructions execute.
TNS object code. The TNS instructions that result from processing program source code
with a TNS language compiler. TNS object code executes on both TNS and TNS/R
systems.
TNS object file. The object file created by a TNS compiler. The file contains TNS
instructions and other information needed to construct the code spaces and the initial
data for a TNS process.
TNS process. A process initiated by executing a TNS or accelerated object file.
TNS shared run-time library (TNS SRL). An SRL available to a TNS process in the OSS
environment. A TNS process can have only one TNS SRL. A TNS SRL is implemented
as a special user library that allows shared global data.
TNS user library. A user library available to TNS processes in the Guardian environment.
TNS word. An instruction-set-defined unit of memory. A TNS word is 2 bytes (16 bits) wide,
beginning on any 2-byte boundary in memory. See RISC word and word.
TNS/R. See NonStop Series/RISC (TNS/R).
TNS /R native C compiler. The C compiler that generates TNS/R object files. Compare
with “TNS C compiler.”
TNS/R native mode. The operational environment in which native-compiled RISC
instructions execute.
TNS/R native object code. The RISC instructions that result from processing program
source code with a TNS/R native compiler. TNS/R native object code executes only on
TNS/R systems, not on TNS systems.
TNS/R native object file. A file created by a TNS/R native compiler that contains RISC
instructions and other information needed to construct the code spaces and the initial
data for a TNS/R native process.
TNS/R native process. A process initiated by executing a TNS/R native object file.
TNS/R native shared run-time library (TNS/R native SRL). An SRL available to TNS/R
native processes in the Guardian and OSS environments. TNS/R native SRLs can be
either public or private. A TNS/R native process can have multiple public SRLs but only
one private SRL.
