During ASPdb programming, sometime it is necessary to clear all the system variables especially during the re-entrance of the same module. That means instead of flowing from one module to the next, the program logic calls for using the same module by modifying some of the properties. Note that all the variables of the modules are separated by the unit number. Therefore, it is not necessary to reset if a different unit number is used !
