Зарезервированные слова отдельных режимов компилятора объединены следующим образом:

  • Режим Turbo Pascal: для использования доступны зарезервированные слова Turbo Pascal.
  • Режим Delphi: для использования доступны зарезервированные слова Turbo Pascal и Object Pascal.
  • Режим Free Pascal: для использования доступны зарезервированные слова Turbo Pascal и Object Pascal.


Зарезервированные слова в Turbo Pascal

Следующие зарезервированные слова встречаются в режиме Turbo Pascal:

ключевое слово описание
and Boolean operator requiring both conditions are true for the result to be true
array multiple elements with the same name
asm start of code written in assembly language
begin start of a block of code
break exit a case statement
case select a particular segement of code to execute based on a value
const declare an identifier with a fixed value, or a variable with an initialized value
constructor routine used to create an object
continue skips an iteration in a for-loop and restart execution at the beginning of the loop
destructor routine used to deallocate an object
div integer divide operator
do used to indicate start of a loop
downto used in a for loop to indicate the index variable is decremented
else used in if statement to provide an execution path when the if test fails
end end of a block of code, a record or certain other constructs]
false boolean value indicating a test failed; opposite of true
file external data structure, typically stored on disc
for loop used to increment or decrement a control variable
function define start of a routine that returns a result value
goto used to exit a segment of code and jump to another point
if test a condition and perform a set of instructions based on the result
implementation define the internal routines in unit
in identifies elements in a collection
inline machine code inserted directly into a routine
interface public declarations of routines in a unit
label defines the target jump point for a goto
mod operator used to return the remainder of an integer division
nil pointer value indicating the pointer does not contain a value
not boolean operator that negates the result of a test
object defines an object construct
of defines the characteristics of a variable
on
operator defines a routine used to implement an operator
or boolean operator which allows either of two choices to be used
packed indicates the elements of an array are to use less space (this keyword is primarily for compatibility with older programs as packing of array elements is generally automatic)
procedure define start of a routine that does not return a result value
program defines start of an application. This keyword is usually optional.
record group a series of variables under a single name
repeat loop through a section of code through an until statement as long as the result of the test is true
set group a collection
shl operator to shift a value to the left; equivalent to multiplying by a power of 2
shr operator to shift a value to the right; equivalent to dividing by a power of 2
string declares a variable that contains multiple characters
then indicates start of code in an if test
to indicates a for variable is to be incremented
true boolean value indicating a test succeeded; opposite of false
type declares kinds of records or new classes of variables
unit separately compiled module
until indicates end test of a repeat statement
uses names units this program or unit refers to
var declare variables
while test a value and if true, loop through a section of code
with reference the internal variables within a record without having to refer to the record itself
xor boolean operator used to invert an or test

Зарезервированные слова в Object Pascal

Object Pascal extends the (Turbo) Pascal language with both support for dealing more easily with objects (object orientation) as well as other newer/more advanced concepts (threads, etc).
In addition to the reserved words in Turbo Pascal, the following reserved words are available in Delphi mode as well:
as
class
dispose
except
exit
exports
finalization
finally
inherited
initialization
is
library
new
on
out
property
raise
self
threadvar
try

Зарезервированные слова в Free Pascal

Зарезервированные слова в режиме Free Pascal включают:


Модификаторы (директивы)

Ниже представлен список модификаторов. Модификаторы не являются строго зарезервированными словами, однако они используются так же, как зарезервированные слова.

Неподдерживаемые модификаторы Turbo Pascal

The reason why these modifiers are not supported is that these modifiers deal with 16 bit code for DOS. In other words, these modifiers have special meaning for 16 bit programming under DOS and Windows 3.x.

As Free Pascal does not support 16 bit code (only 32 and 64 bit), these modifiers are irrelevant in Free Pascal code.

Примечание: However, these modifiers are supported in the DOS crosscompiler present in the FPC development version

More functionality

Apart from the language features provided by the reserved words/keywords mentioned above, there is a lot of functionality available for the programmer in the various libraries:

  • RTL: Run-Time Library, available for all FPC and Lazarus programs
  • FCL: Free Component Library: a core set of libraries available for Lazarus programs and usually for FPC (FPC can be compiled without it, but that only happens on purpose for low-memory embedded systems etc)
  • FPC Packages: other packages provided by FPC
  • Lazarus components: these are Lazarus components that can be dropped on a form and often based on FCL or FPC packages
  • Lazarus utility functions: e.g. the fileutil unit.

Apart from the libraries provided by FPC and Lazarus, there are more libraries/components available:

  • FPC user-supplied units: see the FPC wiki
  • Lazarus CCR: components
  • User-supplied code on the internet: see
