FORTRAN

Input with Vim

Vim's fortran mode starts in column 9, but in IBM Fortran1:

  • Coding forms have 1..5 Statement Number and Statement starting with 7th
  • FORTRAN cards have 1..5 Statement Number, 6th Continuation, and Statement starting with 7th
  • Comments with C in first column followed by two blanks

Available Compilers in [1620.zip]

../../dl/DaveW_paper_tapes/FO003A.PT
../../dl/DaveW_paper_tapes/FO003AP.PT
../../dl/DaveW_paper_tapes/FO003C.PT
../../dl/DaveW_paper_tapes/FO003CP.PT
../../dl/DaveW_paper_tapes/FO005.PT

FO-003A is the compiler (processor in IBM parlance) for paper tape

FO-003C contain the subroutines for paper tape

FO-005 is the pre-compiler for paper tape

What to do after the two compiler runs?

You have to concatenate both paper tape, then you can run it, if you'd have a tape with the subroutines (seem to be mainly floating point functions).
