Code reusable data structures for programs and copy files, using a shorthand format in the Data Structure Editor. Or, code these data structures specifically for your program in the Program Painter. The shorthand format substitutes indentation for level numbers and allows shorthand picture formats. The AMB generators insert level numbers for indentation levels, expand the shorthand formats to full COBOL formats, and insert the necessary punctuation. Alternatively, you can code data structures in the standard COBOL format.
