SPL programs are written with the following set of characters:

  • Uppercase letters A to Z and lowercase letters a to z
  • Digits 0 to 9
  • Special characters ( ) + - * / < > = ! ~ ^ ; : . ' @ % , " # $ & _ | { } ? [ ]
  • White space characters including tabs, spaces, and carriage returns

Identifiers, expressions, statements, and control structures that comprise the SPL language are written with these characters.

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