Odd choice perhaps. Seymour Cray, the 6600 designer, and Garner McCrossen, the programmer of the run compiler, figured that all you needed to put on a command line (actually a punched card in the control deck) was
and the system would invoke the compiler to read the Fortran source cards in the deck and run the program.
There were no compiler options of any significance.
The compiler was written in assembly language for the 6600 and was a remarkable piece of code.
Click on the photo and it will take you to a Google search for more images of the CDC 6600. (Back in the day, I was a systems programmer at NYU on the serial 4 machine in 1965, maintaining the run compiler and library).
