Reserved Words
Reserved words are symbols that have special meaning to the Pascal
language. They are the names of statements, data types, or operators. A
reserved word can be used in a program only in the context for which it
is defined. A reserved word cannot be redefined for use as an
identifier. It may, however, be used within comments or string literals.
A list of reserved words recognized by HP Pascal with a brief description
of each is given in Table 2-2 . A more detailed description of some
of the reserved words follows in this chapter. In some cases, a detailed
description is presented elsewhere in this manual. Table 2-2
provides the location of these instances by word and chapter.
