Hi,
For what it may be worth: Some years ago, we tried finding metrics for 
volume and complexity of ST code. We tried many exotic measures, but ended 
up with counting number of code lines, ignoring pure comment lines. This 
worked when we assumed that a programmer will break complex code into 
several lines, and compress simple code into a single line. It would 
certainly not work if the programmers were in any way rewarded or punished 
for lines of code, and it does not measure productivity. (On my most 
productive days, the number of lines of code goes down).

LOC can be useful as a rough measure of code "volume", but it immediately 
breaks down if you try to define its meaning more carefully.

Regards
