译文

保留字

下面列出Object Pascal中的全部保留字。保留字不能被重定义，也不能作为标识符使用。

and array as asm

begin case class const

constructor destructor dispinterface div

do downto else end

except exports file finalization

finally for function goto

if implementation in inherited

initialization inline interface is

label library mod nil

not object of or

out packed procedure program

property raise record repeat

resourcestring set shl shr

string then threadvar to

try type unit until

uses var while with

xor

除上面列出的保留字外，private、protected、public、published、automated等在对象类型声明中出现的单词/单字，其行为也可保留字一样，但它们被另视为指示字。此外，at和on也具有特殊含义。
