Identifiers
Identifiers in SIMPOL are currently composed of the characters a-z, A-Z, the digits 0-9, and the underscore. They are required to begin with an alphabetic character. The restriction to the character range may be modified in the future although we do not currently foresee supporting right-to-left identifier names or identifiers written using kanji characters.
