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 ...

TREK7 is probably Fortran IV as it dates back to the
early 70ties.
Have a look at the link in my first mail.
