16-bit addressing. Referencing a data item or parameter by using a 16-bit address (also
called standard addressing). Compare to 32-bit addressing.
32-bit addressing. Referencing a data item or parameter by using a 32-bit address (also
called extended addressing). Compare to 16-bit addressing.
abbreviated combined relation condition. A combined condition that results from the
explicit omission of a common subject, a common relational operator, or both in a
consecutive sequence of relation conditions.
accelerate. To speed up emulated execution of a TNS object file by applying the
Accelerator for TNS/R system execution or the TNS Object Code Accelerator (OCA)
for TNS/E system execution before running the object file.
accelerated mode. See TNS accelerated mode.
accelerated object file. A TNS object file that, in addition to its TNS instructions (in the
TNS region) and symbol information (in the symbol region), has been augmented by
the Accelerator with equivalent but faster MIPS RISC instructions (in the MIPS region),
the Object Code Accelerator (OCA) with equivalent but faster Intel® Itanium®
instructions (in the Itanium instruction region), or both.
Accelerator. A program optimization tool that processes a TNS object file and produces an
accelerated object file that also contains equivalent MIPS RISC instructions (called the
MIPS region). TNS object code that is accelerated runs faster on TNS/R processors
than TNS object code that is not accelerated. See also TNS Object Code Accelerator
(OCA).
access mode. The form of file access permitted for a user or process.
actual decimal point. The physical representation of the decimal point position in a data
item, as either a period (.) or a comma (,). Compare to assumed decimal point.
actual parameter. A data item that a calling program passes to a called program. Compare
to formal parameter.
aligned. In native mode, a data item is aligned if its address is a multiple of its size. For
example, a four-byte data item is aligned if its byte address is a multiple of four.
alphabet-name. A user-defined word assigned to a specific character set or collating
sequence or both in the SPECIAL-NAMES paragraph of the Environment Division.
alphabetic character. Any uppercase or lowercase letter or a space.
alphanumeric character. A letter, digit, or hyphen.
