I'd imagine a lot of the problems are due to the increased volume. So that would show up as abends due to exceeding data set size definitions in JCL, VSAM, IMS or DB2 (or even IDMS and the other database technologies in use 20 - 30 years ago.)If the unemployment system is adding a covid related unemployment code then they would need someone to crawl through the code looking for where the logic needed to change in calculating benefit amount, duration of benefits and such.
