Abstract

This invention is directed to a computerized system and method for creating a computer file trademarked as a hot pack to be used to modify object code without the need to halt the executing code. The present invention provides a system called a Development Environment (DE) for a computer programmer. The DE allows for source code to be created, segmented into grains and translated into object code. The source code can then be modified to a second version, also having grains that can be mapped onto the grains of the first version to identify the grains of the first object code that needs to be modified according to the second version of object code.

a computer readable medium; and

,

creating an initial version of source code,

storing said initial version of source code within said computer readable medium,

segmenting said initial version of source code by creating initial grain boundaries that define initial grains having predetermined segments of code within said initial version of source code, and

translating said initial version of source code to an initial version of object code, said object code having object grain boundaries and object grains corresponding to said initial grain boundaries and said initial grains respectively so that initial object code is provided that can be subsequently modified without halting its execution.

9. The system of claim 8 wherein said computer readable instructions include instructions for storing said selected optimization level within said computer readable medium for subsequent retrieval.

10. The system of claim 1 including a crumb associated with said object grain having an active and inactive state so that said object grain will be modified when said crumb is in said active state without halting the execution of said object code.

11. A computerized system for modifying a first version of object code having first grain boundaries and first grains, stored in a computer readable medium, to a second version of object code comprising:

a set of computer readable instructions embodied within said computer readable medium for;

retrieving said first version of source code from said computer readable medium,

duplicating said first version of source code into a second version of source code within said computer readable medium,

creating second grain boundaries associated with said second version of source code defining second grains,

mapping said first grains onto said second grains,

editing said second version of source code,

translating said second version of source code to a second version of object code while maintaining said mapping of said first and second grains,

creating a dynamic list of first grains and corresponding second grains for at least those first grains to be modified according to said second version of source code,

creating a dictatorial having at least one dictum according to said dynamic list and at least a portion of said second version of object code, and,

generating a hot pack according to said dictatorial and at least a portion of said second version of object code so that said hot pack can be distributed in order to modify said first version of object code to said second version of object code without halting the execution of said first version of object code.

12. The system of claim 11 wherein said computer readable instructions include instructions for editing said second grain boundaries so that said second grains can be modified.

13. The system of claim 11 wherein said computer readable instructions include instructions for verifying lexical information of said second version of source code so that lexical errors may be identified in said second version of source code.

14. The system of claim 11 wherein said computer readable instructions include instructions for verifying syntactical information of said second version of source code so that syntactical errors may be identified in said second version of source code.
