This topic describes the character sets that are used by SPL programs.

SPL programs are written by using the following character sets:

  • Uppercase letters A to Z and lowercase letters a to z
  • Digits 0 to 9
  • Special characters:

    ( ) + - * / < > = ! ~ ^ ; : . ' @ % , " # $ & _ | { } ? [ ]

  • Space characters, tab characters, spaces, and carriage returns

Identifiers, expressions, statements, and control structures of the SPL language are written by using these characters.

Note The data that can be manipulated by an SPL program is determined by the character set that the database encoding supports.
