The AMASPZAP service aid, also called SPZAP or Superzap, dynamically updates or dumps programs and data sets. You can use AMASPZAP to inspect and modify instructions or data in any load module or program object in a program library, to dump a load module or program object in a program library, or to update the system status index in the directory entry for any load module or program object. Load modules can be updated in place; when a program object is updated using AMASPZAP, a new copy of the program object is created.
