1. A computer-implemented method, comprising: storing a graphical program, wherein the graphical program comprises a plurality of interconnected nodes which visually indicate functionality of the graphical program; converting the graphical program to an executable program that implements the functionality of the graphical program and which is executable on a portable computing device, wherein the executable program comprises first executable code implementing a call to each of one or more programs, wherein the one or more programs are separate and distinct from the graphical program, wherein the graphical program is designed to be executed by a software execution engine, wherein the portable computing device does not include a software execution engine, and wherein said converting the graphical program to an executable program which is executable on the portable computing device comprises: examining the graphical program to determine portions that require functionality of the software execution engine; and incorporating program instructions into the executable program in response to said examining, wherein the incorporated program instructions enable the portions to execute on the portable computing device without use of the software execution engine; transferring the executable program to the portable computing device, wherein the portable computing device is coupled to a computer; and executing the executable program on the portable computing device, comprising: the executable program invoking execution of the one or more programs on the computer via the implemented calls in the first executable code, wherein the portable computing device communicates with the computer in a wireless manner to enable the executable program to invoke execution of the one or more programs; and executing the one or more programs on the computer in response to said invoking.
