Abstract
In order to improve the efficiency of test and debug procedure based on delarative program understanding of a program described by a logical language, the operation which has been executed for each procedure is grasped. On the basis of information relating to the grasped operation, the operation range of each procedure is expressed clearly by making thick only sides which have actually operated among four sides of a box-shaped figure surrounding each head term and end body term of each clause included in each procedure.
Claims6
An operation range display method for a system which executes a logical language program which includes one or more procedures, each procedure including one or more clauses, each clause including one or more terms, the method comprising the steps of:
- detecting, in response to execution of each of said terms included in said program, an operation status of said term at a time of execution, said operation status indicating whether said term has been executed by call or redo and whether a result of the execution has been successful or not;
- and
- displaying said program and corresponding figures, each of said figures being displayed near a corresponding term of said program so that each figure differs depending upon a corresponding operation status at a time of execution thereof thereby enabling the displayed figures to represent respective operation ranges of respective terms of said program.
