Install: brew install ftnchek

About:
Ftnchek is a static analysis tool designed specifically for Fortran 77 programs. It performs detailed checks for syntax errors, type mismatches, and adherence to coding standards, helping developers maintain clean and correct legacy codebases. It also generates cross-reference listings and detects deprecated constructs.

Key Features:

Syntax and declaration checking
Type consistency verification
Cross-reference generation
Portability and standard compliance checks

Use Cases:

Auditing legacy Fortran 77 codebases for errors
Enforcing coding standards in scientific computing projects

Alternatives:

gfortran – Modern compiler with diagnostics; less focused on legacy style checks than ftnchek
NAG Fortran Compiler – Commercial compiler with rigorous checking; broader than ftnchek's specialized scope
