State Farm, in 1973, was completely dependent on AUTOCODER which was then running on 360/30s and 360/40s in the 25 regional offices, while the new "Real Time" replacement application was still being created (in PL/1). When the "Real Time" system ultimately failed, the next iteration was called "DELTA" as in "Drop Everything, Let's Try Again).
Those AUTOCODER compiles required very long run times and were CPU hogs on the home office 360/165 machines, so a team was assembled to rewrite the compiler in PL/1. The end result was a massive reduction in the compile time. But the team found on instance in which the IBM compiler generated incorrect code, and were going to fix that IBM error, but management decided the team should generate the exact same code as the IBM compiler, so they implemented their compiler to generate that same error. I was NOT a part of this team, but I think that at least one of that team is a semi-frequent poster to this forum.

I might believe AUTOCODER. Would that be 1401, 1410, 7070[1] or 7080 AUTOCODER? [1] By far the most sophisticated of the lot. -- Shmuel (Seymour J.)
