Layout Definition Utility - Defining Repeating Items

Layout Definition Utility - Defining Repeating Items

The Layout Definition Utility uses the repetition level (Lv) column and the repetitions (Repeat) column to communicate repeating groups of items, usually defined in COBOL OCCURS clauses.
The Layout Definition Utility only displays elementary items. To indicate that a group of items is repeated, the utility inserts a repetitive definition line immediately before the repeating group. This line only contains a level number and a repetition count.

The repetition level indicates the level of nesting of repeating groups. The repetitions column indicates the number of times the group is repeated. The level number is incremented in the line after the repetition line.
The utility supports up to 7 levels of repetition nesting.

(Example) Group Item option is "Hidden". see COBOL Library Analysis Option
