Good morning, BSpeed;
Yup. FORTRAN 2.4, a version not too different from the classical FORTRAN IV that McCracken wrote about. (FORTRAN; FORmula TRANslation, a computer programming language intended for lots of scientific data reduction.) The guys at CDC developed it for us. Had to do it many times in the lab. As mentioned, lots of time up on the second floor of Building 46 in front of an IBM Model 26 Card Punch.
