Fundamental Syntactic Elements This topic introduces the Delphi language character set, and describes the syntax for declaring:
Identifiers
Numbers
Character strings

The Delphi Character Set The Delphi Language uses the Unicode character set, including alphabetic and alphanumeric Unicode characters
and the underscore. It is not case-sensitive. The space character and the ASCII control characters (ASCII 0 through
31 including ASCII 13, the return or end-of-line character) are called blanks.
Fundamental syntactic elements, called tokens, combine to form expressions, declarations, and statements. A
statement describes an algorithmic action that can be executed within a program. An expression is a syntactic unit
that occurs within a statement and denotes a value. A declaration defines an identifier (such as the name of a function
or variable) that can be used in expressions and statements, and, where appropriate, allocates memory for the
identifier.
