PURPOSE:To minimize the change and the addition to a main program, by inserting only the calling instruction of the information collecting subroutine to an optional address requiring the collection of information for the main program and storing previously the information collecting parameter in a different table. CONSTITUTION:A subroutine 1-2 that collects the information is called out at an optional stage of a main program 1-1 to collect the variable data, the contents of a register, etc. In such system, only an instruction JSR is stored in an address (x) of the program 1-1 to read the routine 1-2. A table is provided to store the information collecting parameter along with a stack register 1-5 that stores a return address (y) of the program 1-1 when the routine 1-2 is called. Thus when the routine 1-2 is called out, the address (y) set to the register 1-5 is extracted. The index is carried out to a table 5 through the address (y) to extract the information collecting parameter. Then the collection is carried out for the information of a type that is designated by the above-mentioned parameter. |
