Conventions in syntax explanations

The following table explains the symbols used in this manual:

Symbol	Convention
`\|`	In syntax explanations, a vertical bar separates multiple items, and has the meaning of OR. For example: `A\|B\|C` means `A`, or `B`, or `C`.
`{ }`	In syntax explanations, curly brackets indicate that only one of the enclosed items is to be selected. For example: `{A\|B\|C}` means only one of `A`, or `B`, or `C`.
`[ ]`	In syntax explanations, square brackets indicate that the enclosed item or items are optional. For example: `[A]` means that you can specify `A` or nothing. `[B\|C]` means that you can specify `B`, or `C`, or nothing.
`...`	In coding, an ellipsis (...) indicates that one or more lines of coding have been omitted. In syntax explanations, an ellipsis indicates that the immediately preceding item can be repeated as many times as necessary. For example: `A, B, B, ...` means that, after you specify `A, B,` you can specify `B` as many times as necessary.
`underline`	Underlined characters indicate the default value.
Δ	A triangle indicates a space character. Δ₀ indicates zero or more spaces or tabs. Δ₁ indicates one or more spaces or tabs.
`~`	The item that precedes this symbol must be coded in accordance with the rule expressed within the symbols <> or (()) following the ~ symbol.
`< >`	Code the item in accordance with the lexical elements enclosed in the angle brackets: numeric Numeric from 0 to 9. Unless otherwise specified, a number is decimal. alphabetic Letter in the range A to Z, or a to z. alphanumeric Letter or number. Unless otherwise specified, a number is decimal. unsigned integer Number. A decimal unless otherwise specified. hexadecimal Hexadecimal number (0 to 9, or A to F).
`(( ))`	Double parentheses enclose the range of specifiable values.
`<< >>`	Double angle brackets enclose the default assumed by the program when no value is specified.
