T3 Fortran(ID:5845/tfo001)

The compiler was embedded within Hartran, a Fortran environment designed at
AERE Harwell for their Atlas under the direction of Dr. Ian Pyle. Hartran
provided a symbolic loader capable of combining Fortran (and potentially other)
subroutines that had been separately compiled, and was the only such system
program available on any of the Atlas family. Separate compilation was of course
a natural extension of the earlier pioneering work at Cambridge with
subroutines, and vital for any large program.

I personally had migrated the Hartran system from Atlas to Atlas 2, having
earlier written the code generation phase of the first Atlas Fortran compiler at
Harwell.
