pTAL compiler
language excludes architecture-specific TAL constructs and includes new constructs
that replace the architecture-specific constructs.
Contrast with TAL.
pTAL compiler. An optimizing native-mode compiler for the pTAL language.
public dynamic-link library (public DLL). Optional native-mode executable code modules
available to all native user processes. A TNS/E public library that is specified in the
public library registry, supplied by HP or, optionally, a user.
reduced instruction-set computing (RISC). A processor architecture based on a
relatively small and simple instruction set, a large number of general-purpose registers,
and an optimized instruction pipeline that supports high-performance instruction
execution. Contrast with complex instruction-set computing (CISC)
RISC. See reduced instruction-set computing (RISC).
RISC instructions. MIPS RISC instructions. See also MIPS RISC instructions.
RISC word. An instruction-set-defined unit of memory. A RISC word is a MIPS RISC word.
Contrast with TNS word and word. See also Itanium word and MIPS RISC word.
RTL. See run-time library (RTL).
RTLDECS. A file, provided by the TNS CRE, that contains external declarations for CRELIB
functions whose names begin with RTL_.
RTLRDECS. A file, provided by the native CRE, that contains external declarations for RTL
functions, data, and data structure declarations in pTAL.
run-time environment. The services provided by run-time library functions and data objects
(data blocks and pointers) to a program at run-time.
run-time library (RTL). A collection of functions that supports requests for services such as
I/O and heap management, math and string functions, exception handling, and error
reporting.
saveabend file. A file containing dump information needed by the system debugging tool.
(In UNIX systems, such files are usually called core files or core dump files.) A
saveabend file is a special case of a save file.
See also save file and process snapshot
file.
save file. A file created by the system in response to a command from a debugger. A save
file contains enough information about a running process at a given time to restart the
process at the same point in its execution. A save file contains an image of the
process, data for the process, and the status of the process at the time the save file
was created.
A save file can be created through an Inspect SAVE command at any time. A save file
called a saveabend file can be created by when a process’s SAVEABEND attribute is
