I mostly learned Fortran from "IBM System/360 and System/370
Fortran IV Language." Later I had the McCracken book from
the library. At some point I learned the 'LIST' option from
the compiler which prints out the generated assembly code.
I also had some assembly (Fortran callable subroutines) to
read and after not so long tried writing my own.
S/360 assembler isn't quite as readable as VAX but isn't
so hard either.
