Identifiers

Description

Identifiers are the names you give to symbols, collections, sheets, or fields. All identifiers are case-insensitive (this means that Gramble treats nouns as the same as Nouns or NOUNS). There are a small set of characters that cannot be used in identifiers including: >, <, %, (, ), / (the slash operator), (space), . (this is used for intersheet and collection reference).

A valid identifier must begin with either a letter, mark (any Unicode combining mark/diacritic/accent), a modifier symbol (accents and diacritics, modifier arrows and marks, or spacing signs), or _ (underscore). The subsequent characters may be drawn from the set of valid first characters, or be a number, _, @, #, $, -, ', or ".
