Built-in operators

• Exponentiation: According to Extended Pascal, GNU Pascal supports exponentiation operators pow and ** which do not exist in Borland Pascal. You can use x pow y for integer and x ** y for real or complex exponents; the basis may be integer, real or complex in both cases.
• Address operator: GNU Pascal accepts Borland's @, but also & as an address operator.
• GNU Pascal has a symmetric set difference operator set1 >< set2. See See section GNU Pascal extensions for more about this.
