Abstract: Methods for minimizing starting run time of application software are presented. Application software may be divided into blocks or components. If divided into blocks, a block may include a block loader function for calling another block having an instruction otherwise not included. Application software is transmitted to a client, which may begin execution as the application software is being transmitted. The client may encounter a block loader function causing the server to transmit the block that includes the instruction. In response to receiving the transmission, the client runs the application software using the instruction. If the application software is divided into components, each component may be encapsulated by a handler. A component may be divided into sub-components. A function included in a sub-component may be dependent upon a function in another sub-component. If the function is called, then the function(s) dependent upon the called function are transmitted to the client.
