Even more moot. Most of the work that we were doing at NASA was in
FORTRAN. A FORTRAN compiler that runs on current machines is NOT
If the source code is available, then it can be used, NOT for compiling,
but for determining the structure of the data. If the source code is NOT
available, then the structure of the data must be manually determined.
After that, new software can be written to work with it.
A REAL programmer can write a FORTRAN program in any language.
