Now the Fortran compiler I remember using with the 1401 was quite different from the one that was mentioned here - 3 passes and card intermediate. There was a clever Fortran compiler for the 1401 - it was written up in IBM Systems Journal - that was on tape, did something like 30 passes. The idea was that the Fortran source sat in memory initially, and each pass of the compiler transformed what was in memory into something else that the next pass would work on. The passes were in sequence on the tape, so the user's program just sat there as the compiler was run over it.
