Procedure length is measured by logical lines of code (LLOC).
Comments and whitespace are not counted.

Source file sizes

Average source file size

Average length	145	LINES
Average kilobytes	5.6	kB

Smallest and largest source files

Longest file	249	LINES	PicMain.bas
Shortest file	50	LINES	PicInfo.cls

Largest file	10.2	kB	PicMain.bas
Smallest file	1.9	kB	PicInfo.cls

Line counts in this section are physical line counts (LINES).

Complexity

Cyclomatic complexity

Complexity	Procs	%	Distribution	Description
1- 4	24	92%	******************	Simple procedure
5-10	1	4%	*	Well structured, stable
11-20	0	0%		More complex
21-50	1	4%	*	Complex, alarming
51-	0	0%		Error-prone, troublesome
Total	26	100%

Cyclomatic complexity (CC) = Number of decisions + 1
Recommended range: 1-10

Average complexity	2.65
Decision density	0.27	DECDENS=CC/LLOC, complexity per a line of code
Total complexity	44	TCC = total number of decisions + 1

Depth of conditional nesting

DCOND = Maximum nested conditional statements in procedure.

Recommended maximum	5
Actual maximum	5
Too high (DCOND > 5)	0	procedures (0%)
Average DCOND	0.8

Other procedural complexity values

Average SFOUT	0.81	Structural fan-out
Average DLOOPS	0.00	Depth of looping
Average IFIN	2.42	Informational fan-in
Average IFIOUT	1.35	Informational fan-out

Logical lines of comment LLOC'	173	24%
Lines of whitespace LLOW	173	24%
Total logical lines LLINES	717	100%

Full-line comments	173	75%
End-of-line comments	58	25%
All comments	231	100%

Comment contents
Meaningful comments MCOMM	224	97%
Meaningless comments	7	3%
All comments	231	100%

Comment density
MCOMM per code line (MCOMM%)	60%		MCOMM/LLOC

Logical line: Lines continued on several lines are counted as one logical line.
Lines excluded by conditional compilation are not included in the logical line counts.
A meaningful comment contains text rather than just whitespace or punctuation.
