The use of callback functions when executing intermediate instructions in a virtual machine is described. The virtual machine receives and evaluates intermediate instructions. The virtual machine evaluates the instructions based a function table referencing definitions of the functions. A callback is loaded into the virtual machine platform, and a callback loader modifies the function table to cause a function in the table to point to the callback instead of the standard definition. Thus, when the intermediate code is evaluated, it is evaluated based on the modified functionality of the callback rather than the standard definition.
