I programmed main frames in the 1960's and 70's. The problem is mainly in COBOL. 2 digits used for Year to save space on disks and tapes and also save on time reading dates into buffers from these mag tapes and disks. Input was on punched cards. Key 2 digits only saves time.It was not a mainframe problem as such. In 1970 I designed a system on IBM using PL/1. Dates were stored in 2 bytes only as a number of days from an arbitrary start point. A software routine would be used to encode and decode the date. This system will last until 2027. 57 years should be enough for any system to last.
