Abstract
A method and apparatus generate computer executable code as one or more code portions, detect a number of processing operations required to reach one or more predetermined stages in execution of each code portion, and associate with each code portion one or more progress indicators, each representing a respective execution stage of the one or more predetermined stages within execution of that code portion. Further aspects include, when a current execution stage of the program code is at least at the execution stage represented by the progress indicator, a first operation may be performed, and when the current execution stage of the program code is before the execution stage represented by the progress indicator, a second operation different from the first operation is performed.
