Hy Perteks is concerned that old courses for obsolete versions of software are cluttering the drives. Create and print the DELETE SOFTWARE COURSE display. Entry fields are the SOFTWARE TITLE, OPERATING SYSTEM, and VERSION NUMBER. The program displays a line for each course taught for the software version. The first column contains an entry field with a D (for delete) presented as a default. Placing a space in the field will prevent the record from being deleted. The other columns for each line are COURSE TITLE, LEVEL, and CLASS LENGTH. Add a meaningful operator message.
