Allow MOD directive to accept only the standard base header parameters There are cases where only the standard OS9 module header fields are to be provided. This could be, for instance, in the case of a nonstandard user type module. So allow the execution offset and data size fields to be omitted entirely and handle the module length correctly as well.
