The restricted acts in respect of a computer program provided for in Section 11B(e) of the Copyright Act, namely "letting, or offering or exposing for hire by way of trade, directly or indirectly, a copy of a computer program" does not apply to literary works. These restricted acts are of great importance in regard to the commercial exploitation of computer programs and it was considered desirable that computer programs should enjoy this form of protection which was not available to them while they were treated as a species of literary work.
