1. A method for execution by a dispersed storage processing module, the method comprises: receiving a first request to store a program; determining first error coding dispersal storage function parameters; encoding a data segment of the program in accordance with the first error coding dispersal storage function parameters; determining whether a second request to store the program is received; when the second request is not received, encoding a second data segment of the program in accordance with the first error coding dispersal storage function parameters; when the second request is received, changing the first error coding dispersal storage function parameters based on the second request to produce second error coding dispersal storage function parameters; and encoding the second data segment in accordance with the second error coding dispersal storage function parameters.
