• Lines of code
• Number of embedded SQL lines
• Number of blank lines
• Number of comment lines
• Total number of lines
• Number of decision elements
• Cyclomatic complexity
• Fan out

The above values are then summed to provide their respective project metrics. In addition, other project metrics calculated include:

• Average project cyclomatic complexity
• Project fan out metric (with and without leaf nodes)
• Total number of procedures and functions
• Total number of source code and header files
• Lines of code in source code and header files
• Total number of source code files unit tested
• Number of embedded SQL statements
• Lines of code unit tested
• Percent of files unit tested
• Integration Test Percentage

The Integration Test Percentage (ITP) provides a numeric value indicating how much of the project's source code has been tested and can be used to better prepare for Formal Qualification Testing (FQT).

Output from Metrics4FORTRAN can easily be imported into a spreadsheet program to graphically display the data. Metrics4FORTRAN can also flag warnings if the lines of code or the cyclomatic complexity value exceeds a specified maximum.

Metrics2GIF generates GIF graphics for Metrics4FORTRAN summary data which can then be viewed using a web browser.
