System and Other FunctionsParametersstringA quoted string to validate as a legal identifier name. The characters a valid string can containdepend both on the type of identifier to validate (specified by n), the language mode (lang),and the definition of your locale. By default, the following are valid identifier characters inCaché:• Uppercase letters: A through Z (ASCII 65–90)• Lowercase letters: a through z (ASCII 97–122)• Letters with accent marks: (ASCII 192–255, exclusive of ASCII 215 and 247)• Digits: 0 through 9 (ASCII 48–57) subject to positional restrictions for some identifiers• The percent sign: % (ASCII 37) subject to positional restrictions for some identifiersnAn integer code specifying the type of name validation to perform:548 Caché ObjectScript Reference

The first character of a valid identifier mustbe either a percent sign (%) or a valid letter character. The second and subsequent charactersof a valid identifier must be either a valid letter character or a digit.If n = 1, an identifier that passes validation may be used for routine names. In CachéObjectScript routine names, the first character must be either a percent sign (%) or a validletter character. The second and subsequent characters of a routine name may be either apercent sign (%), a valid letter character, or a digit. Thus, routine names differ from othertypes of names because they can include a percent sign (%) anywhere in the name.Caché ObjectScript Reference 549
