Margins A & B Restrictions on data placed in these margins will no longer be requirements, only recommendations

Identification Division Only paragraph permitted in this division will be the Identification Division Name Lengths Increased from 30 to 60 characters

Comments In-line comments will be allowed after a *> symbol Arithmetic Operators Spaces will not be required around operators

Sort The SORT keyword can now be used on both tables and files
