ASSIGN. An HP Tandem Advanced Command Language (TACL) command you can use to
associate a file name with a logical file of a program or to assign a physical device to
logical entities that an application uses.
BIND. A program invoked during system generation that creates TNS object (file code 100)
system code files and system library files.
binding. The operation of collecting, connecting, and relocating code and data blocks from
one or more separately compiled TNS object files to produce a target object file.
BINSERV. A version of the Binder program that is integrated with the C, COBOL85,
FORTRAN, and TAL compilers.
block. A grouping of one or more system enclosures that an HP NonStop™ S-series
system recognizes and supports as one unit. A block can consist of either one
processor enclosure, one I/O enclosure, or one processor enclosure with one or more
I/O enclosures attached.
checkpoint. The operation by which information in the primary process of a NonStop
process pair is sent from the primary process to the backup process. See also stack
checkpoint. and takeover point..
code block. The smallest independently relocatable piece of a program. Code blocks
contain executable machine instructions and possibly inline constant data. Compare
with data block.
collector. See spooler collector.
COMMON block. A data block whose contents can be referenced by all modules.
Common Run-Time Environment (CRE). A set of services, implemented by the CRE
library, that supports mixed-language programs on D-series systems. Contrast with
language-specific run-time environment.
Common Run-Time Environment (CRE) library. A collection of routines that supports
requests for services managed by the CRE, such as I/O and heap management, math
and string functions, exception handling, and error reporting. CRE library routines are
used by D-series C, COBOL85, FORTRAN, and Pascal run-time libraries.
compilation unit. The object code produced by a single run of a compiler.
compiler directive. A compiler option with which you control compilation, compiler listings,
and object code generation. For example, compiler directives enable you to compile
parts of a source file conditionally or to suppress parts of a compiler listing.
connection. With respect to the CRE, a connection is a path managed by the CRE from a
process to a Guardian file. Each connection is a unique path to the same Guardian file
