Rules for naming identifiers

• The identifier length should be limited to 10 characters including periods and excluding $

(dollar sign) and % (percent sign) suffixes.

• Every type of variables can contain up to 255 identifiers.

• A reserved word cannot be used by itself for an identifier name, but can be included

within an identifier name.

• An identifier should not start with a numeral character or the character string

FN. If start-

ing with an

FN, the character string will be treated as a function identifier defined by the

DEF FN statement.

Examples of identifiers:
