OUTPUT METHOD FOR INFORMATION OF PROGRAM VARIABLE

PROBLEM TO BE SOLVED: To solve the problem, in a conventional system, that it is difficult to extract names of other variables necessary to change simultaneously to detect dropouts, to find errors and to prevent errors of variables if there are other variables necessary to change simultaneously together with changes of variable names specified by the variables that are not having nothing to do with transmitting relations, not having similar names and not existing on the same lines. SOLUTION: An output method for information of program variable comprises a means to specify the variable names of analyzing objects by inputting a source program, a means to specify a range to extract the names of other variables, a means to extract using points of the names of the objects, a means to extract other variable names used within the specified range and a means to output the extracted other variable names.
