The IBM 1401 COBOL compiler produced excellent code in 1966. And you can get a "tape" for it and run it in SimH i1401. Statements like "MOVE A TO B." compiled into one instruction. "ADD A TO B GIVING C" compiled into two instructions. Regardless of the number of digits in the (non- display) picture. Display pictures resulted in one "Move Characters and Edit" instruction. It's almost as if the 1401 was designed to run COBOL, but it appeared one year before the DoD 60 COBOL standard. The Burroughs 2500/3500 systems also catered for COBOL quite effectively.
