Claims

[Scope of utility model registration request]

In a program debugging support mechanism that detects and corrects errors in a language system in which a source program is translated into intermediate language by an intermediate language compiler and this intermediate language program is executed by an intermediate language interpreter, the line number of the source program and the source A line number conversion table memory is provided to record a correspondence table between the line numbers of the intermediate language program translated into intermediate language, and a keyboard is provided in this line number conversion table memory to support the line number of the execution interruption in the source program. An interrupt location register is provided for storing the execution interrupt position in the intermediate language program based on the line number output from the line number conversion table memory, and the line number and intermediate language stored in the interrupt location register are also provided. A comparator is provided to compare the line number of the program being executed every instruction interpretation execution cycle, and this comparator outputs a match signal to interrupt the execution of the intermediate language interpreter at an arbitrary position. A program debugging support mechanism featuring:
