QCMP058. FFMAIN: Force-Field Maintenance by D. F. DeTar, Department of Chemistry, Florida State University, Tallahassee, Florida 32306

FFMAIN is a program for the processing of a force field in a machine-readable format. The documentation is presented in the program FFMAIN.FOR. DETSB.DAT is an example of a force field in the proposed format. FFMAIN performs extensive error checking, and it puts all entries into a defined sorted order. It provides a convenient tool for providing a definitive version of a force field and documenting modifications. The program has been compiled with the Lahey F77L FORTRAN compiler; earlier versions have been compiled with the Microsoft FORTRAN version 4.0 . The EXE file requires an 8087 and takes about 520 Kb of memory to run. Two file-opening routines are provided: one for the Lahey compiler, the other for the Microsoft compiler.

FORTRAN 77 (Microsoft 4.0) Lines of Code: 3371
