There were Fortran 66 and 77 compilers under which it wouldn't have
worked.

The OP needs to fix the program, which probably means learning more
about Fortran.

Agreed, and for definiteness, from the little we were told about Jim's program it looks like implicit types are handled differently in different subprograms, e.g. IMPLICIT REAL*8(a-h,o-z) vs. no IMPLICIT statement.
