A research on and the realization for the VAX/VMS disassembler system
Liu Zhijing Huang Luguang Zhao Yuanzhe
This paper introduces a disassembler system which is designed by ourselves and can rununder the VAX/VMS operating system. The system can eradicate the protecting mechanismof DCBUG on system programs and it can be monitered by VMS DCBUG.Also,the systemprovides a multi-function disassembler,which can recongnize the control flow , and disassem-ble the whole moduler from the given entrance address automatically. The attached symbolmakes the result much close to the assembler source program of M ACRO Language. Further-more it can give a calling relationship among the modulers. In thispaper we have explained thedata structure and major dynamic characteristics of VMS,and descriped the major realizationprinciple , the major moduler description and the diagram of the system.
