* Key to Terms *
* *
******************
Clarity
-------
Metrics that indicate how easy it is likely to be
to read and understand the purpose of a source code module or procedure:
* Executable ref. Lines
* Total Comments
* Comments in Headers
* Comments in Declarations
* Comments in Executable Code
* Blank Lines
* Total Comments/Exe. Lines
* Declaration Comments/Exe. Lines
* Code Comments/Exe. Lines
* Average Length of Basic Blocks
* Unique Operands
* Total LCSAJs
* Depth of Loop Nesting
* Expansion Factor
Testability
-----------
Metrics that indicate the amount testing that will be required,
particularly with respect to achieving high Dynamic Coverage :
* Knots
* Cyclomatic Complexity
* Executable reformatted Lines
* Number of Basic Blocks
* Total Operands
* Number of Loops
* Procedure Exit Points
* Number of Procedures
* Total LCSAJs
* Unreachable LCSAJs
* Maximum LCSAJ Density
* Unreachable Lines
* Unreachable Branches
* File Fan in
* Fan Out
Maintainability
---------------
Metrics that indicate the level of consideration that must be given
to modifying a source code module or procedure:
* Essential Knots
* Essential Cyclomatic Complexity
* Knots
* Cyclomatic Complexity
* Vocabulary
* Number of Procedures
* Total LCSAJs
* Unreachable LCSAJs
* Maximum LCSAJ Density
* Unreachable Lines
* Unreachable Branches
Metric results Pass/Fail indicators.
------------------------------------
The display of Pass and Fail indicators is controlled by two environment variables:
=====================================================================
RESULT ENVIRONMENT FLAG INDICATOR
=====================================================================
Pass SHOW_METRIC_PASS (P)
Fail SHOW_METRIC_FAIL (F)
Upper and lower limits for a "Total for <file>" metric can be derived from the
upper and lower limits for a procedure where appropriate.
This is achieved using the 'c' marker in the Metrics Data File.
The base for this calculation is currently variable between files:
(Number of procedures in each source file)
