identifier

A sequence of letters, digits, and symbols which the compiler recognizes as a programmer-defined name of some entity. In 4GL, an identifier can include letters, digits, and underscore symbols ( _ ). It must have either a letter or an underscore ( _ ) as the first character. It can be up to 50 characters in length but the first seven must be unique among similar program entities that have the same scope of reference. 4GL does not distinguish between upper and lowercase letters. Types of identifiers include variable names, cursor names, function names, report names, table names, window names, form names, prepared statement names, and report names.
