USING RANGE VALIDATION IN ASSEMBLY LANGUAGE PROGRAMMING

摘要

Embodiments of the present invention provide a method, system and computer program product for USING range validation during assembly of an assembly language program. In an embodiment of the invention, a method for USING range validation during assembly of an assembly language program has been provided. The method can include parsing assembler language source code loaded for assembly in an assembler executing in memory of a computer. The method also can include identifying a USING statement in the source code establishing a base address as the content of a register. Finally, in response to additionally identifying a subsequent statement in the source code that modifies the content of the register, a warning of an invalid USING range can be generated.
