UNIX FORTRAN 77 to COMPAQ FORTRAN 77 Conversion of a Program

I have a FORTRAN program that calculates laminated composite properties which accepts constituent properties of fiber and matrix properties and outputs effective composite properties of laminated composites. It is written in FORTRAN 77 of UNIX operating system originally. But I need it to convert to COMPAQ FORTRAN. I will provide ficticious input data of fiber and matrix properties as well as laminated ply configuration to debug or to test-run the program. The task is: PHASE I (1) Understand the flow of the logic in the existing FORTRAN program. (2) Ask what input data is need to create a test run of the program. (3) Run the program in COMPAQ FORTRAN. (4) Provide a simpler version of the program by selecting subroutines in the existing program. (Select a group of constituent property and produce effective properties of specified laminates.) PHASE II If every thing goes well for the tasks in PHASE I. Further modification of the program will be forthcoming. (It is not discussed at this point.) PHASE II If everything of the tasks in PHASE I resolves well, I will have PHASE II tasks, which is not discussed here.
