Format Definitions of Lines

Backus Naur (BNF) notation is used for the formal format definitions of the follow-

ing lines. The areas enclosed by < > are nonterminal symbols, showing that the left

side of ::= is replaced with that of the right side. In addition, this replacement is

performed recursively.

The following notation rules are observed:

• Enclosing in [] denotes a termination symbol.

• [CR] indicates a return code.

• [SPACE] indicates a space.

• [TAB] indicates a tab code.

• <keyword> indicates an annexed table.

• The limitations of the keyword and parameter set are given in annexed tables.

• Keywords are case sensitive.

• The limits for the number of columns and characters are specified separately.

• The units used for numbers are described separately.

• Information regarding other limitations is described separately.

• Refer to specification JIS X 0606 for the definitions for <a 1 character> and <d 1

character>. Kanji characters can also be used. Generally, every command has the following

configuration: <line>::=<keyword><parameter list>[CR].

Tokens such as keywords and parameters are separated by one or more blank

spaces, which have the following meanings.

• Space code (0x20)

• Horizontal tab code (0x09)

• Vertical tab code (0x0b)

• Home feed (0x0c)

• Line feed (0x0a)

Each line consists of one line by the line feed code (0x0d).

The definition of each line is shown below.

• Words not enclosed by < > refer to reserved words or the operator input by the user.

• [CR] indicates the line feed code (0x0d).

• [SPACE] indicates a blank space (0x20).

• See standard specification JIS X 0606" for a definition of <a 1 character> and <d 1

character>.
