Abstract
A computer aided software engineering tool is disclosed which is particularly well adapted to identify potential Assembly language source code errors resulting from incorrectly used symbolic and literal address constructs. This objective is achieved by providing a debugging program which has a complete awareness of the specific machine interfaces, conventions and symbol sets. By essentially stepping through the Assembly language statements (without regard to neighboring statements), the debugging program is able, through such examination, to identify, in the Assembly language program under study, specific instances of the use of statements containing possibly incorrect symbolic or literal address constructs and to run closely related additional tests. The programmer may then examine the denoted Assembly language code to determine if a genuine error exists.
