In the development of large systems, subsystems and applications, errors may be detected in macro-instructions used throughout the system, subsystem or application being developed. Such an error has usually required re-assembly or re-compilation of all the modules using the erroneous macro-instruction, followed by a rebuild of the system. This procedure may take from a day to a week. When the error detected in the macro prevents further testing of the system, subsystem or application, that time required to re-compile, re-link and rebuild the system delays the test schedule directly. In a system that uses macro-instructions heavily, such as MVS/VTAM, several such delays impact the ability of the developing group to ship tested, quality-level code according to the original schedule.
