The SyzCMD/z program is also available because of an agreement we have with IBM to ADCD users at for only 5% of the retail price (which is already very low). It does everything that the CBT Commands program on file 19 does, plus adds more than twice the number of "extra" features. One of them

I had a similar story. On a 370/138 at an auto insurance company, the rating program (vendor supplied) would immediately "eat the machine". In those days, there was an actual CPU meter on the console. Whenever this job would run the meter "pegged" for the duration. Basic logic was input pre-proc
