`
`1217. To analyze a program to
`profile \pr<3’l‘il\
`determine how much time is spent
`in different
`parts of the program during execution.
`Profiles for Open Systems Internetworking
`Technology \pr6‘lTlz for 6‘pan sfstamz in‘tor—
`net’wor—kéng tek-nol‘a~jé\
`72. See POSIT.
`prograin \pr6’gram\
`71. A sequence of instruc~
`tions that can be executed by a computer. The
`term can refer to the original source code or to the
`Also
`executable
`(machine
`language) version.
`called software. See also program creation: rou-
`tine, statement.
`
`progrzun card \pr6'gram kard‘\
`ROM card.
`
`17.. See PC Card,
`
`71.
`
`See
`
`kar‘ trij\
`
`program cartridge \pro’gram
`ROM cartridge.
`program counter \pr6’gram koun‘tar\ 12. A regis—
`ter (small, high—speed memory circuit Within a
`microprocessor) that contains the address (loca
`tion) of the instruction to be executed next in the
`program sequence.
`7-2. The
`program creation \pr€>’gram kre—a‘shan\
`process of producing an executable file. Tradition-
`ally, program creation comprises three steps: (1)
`compiling the high—level source code into assem-
`bly language source code;
`(2) assembling the
`assembly language source code into machine»
`code object files; and (3) linking the machine~code
`object files with various data files, run—time files,
`and library files into an executable file. Some com-
`pilers go directly from high—leve1
`source
`to
`machine~code object, and some integrated devel~
`opmcnt environments compress all
`three steps
`into a single command. See also assembler, com-
`piler (definition 2), linker, program.
`program file \pr6’gram lTl‘\ a. A lisk file that
`contains the executable portion(s) of a computer
`program. Depending on its size and complexity,
`an application or other program, such as an oper-
`ating system, can be stored in several different
`files, each containing the instructions necessary for
`some part of the programs overall functioning.
`Compare document file.
`71. A
`program generator \pr6’gram jen\or—E1—t;>r\
`program that creates other programs (usually in
`source code) based on a set of specifications and
`relationships given by the user, Program genera-
`tors are often used to simplify the task of creat~
`
`ing an application. See also /iGL, application
`generator.
`
`77. A copy,
`program listing \pr6’gram li‘steng\
`usually on paper, of the source code of a program.
`Some compilers can generate program listings
`with line numbers, cross~references, and so on.
`
`72. The logic
`program logic \ program loj‘ik\
`behind the design and construction of a pro-
`gram—-——that is, the reasons it works the way it does.
`See also logic error.
`programmable \pr6—gram'o—bl‘\ aaf/'. Capable of
`accepting instructions for performing a task or an
`operation. Being programmable is a characteristic
`of computers.
`programmable function key \ pr<')—gram‘a—bl funk
`shon ké‘\ a. Any of several, sometimes unla-
`beled, keys on some third-party keyboards that
`allow the user to “play back” previously stored
`key combinations or sequences of keystrokes
`called macros. The same effect can be achieved
`
`standard keyboard and a keyboard
`with a
`enhancer, the latter of which intercepts the key»
`board codes and substitutes modified values; but
`programmable
`function keys
`accomplish this
`without requiring RAM-resident software. Com~
`pare keyboard enhancer.
`\pr6—gi-am‘-
`programinable interrupt controller
`a~bl
`in’tar—upt kan—trE>‘lar\
`71. An Intel chip that
`handles
`interrupt
`requests CIRQS).
`IBM AT
`machines use two programmable interrupt con-
`trollers to accommodate a maximum of 15 IRQS.
`The programmable interrupt controller has been
`replaced by the advanced programmable interrupt
`controller (APIC), which supports multiprocess-
`ing. Acronym: PIC (P‘I—C’). See also IBM AT, IRQ.
`programmable logic array \pi'o~gi‘aina—l3l
`loj’ik
`ar—a‘\
`77.. See field—programmable logic array.
`programmable logic: device \ pr6~gram‘9—bl l0j’—
`ik da—vis‘\
`71. A logic chip that is programmed by
`the customer rather than by the manufacturer. Like
`a gate array, a programmable logic device consists
`of a collection of logic gates; unlike a gate array, a
`programmable logic device need not have its pro~
`gramming completed as part of the manufacturing
`process. Acronym: PLD (P‘L—D’). See also logic
`chip. Compare gate array.
`prograimnable read~only rneinory \ prr')~gram‘-
`a—bl réd‘6n‘lé mem’ar—é\
`-17.. See PROM.
