The TREK7 sources compile perfectly with: *fortran /nof77 treka.for*
The VMS HELP says: *$ help fortran /nof77 FORTRAN /F77 (D) /NOF77 Controls whether FORTRAN-77 interpretation rules are used for those statements that have a meaning that is incompatible with FORTRAN IV-PLUS. The default is /F77. If you specify /NOF77, the compiler selects FORTRAN IV-PLUS interpretations in cases of incompatibility.* Looks like it's really FORTRAN IV, but maybe with some VMS specifics and extensions ...
