*YI: Index Directives

An index directive specifies an entry in the help display index; if any index entries are present the help display program will automatically build an index from them. Each index entry points to a label in the text body.

Label name: must be a unique identifier, up to ten characters long, of an index entry. For each *YI: entry a corresponding *YH: label entry is required.

Index entry text: The text specified in columns 18-80 will be displayed in the help text as the index entry.

Note: If the index entry text has a display attribute, that is, is highlighted or underlined, then it should not start before column 19 (to allow for the display attribute byte).
